Study proves that you can secretly hijack an older Mac's webcam

iSeeYou MacBook webcam control
If you believe common wisdom, it shouldn't be possible to take over most webcams without alerting users. The indicator LED is supposed to be hack-proof, after all. However, a pair of Johns Hopkins researchers have recently published aresearch paper showing that it's possible to control the camera while keeping the indicator dark. Their proof-of-concept app, iSeeYou, reprograms a controller chip on pre-2009 Macs to separate the camera and LED functions; users can flick the light on and off like a switch. Apple is aware of the issue with its own systems, but it hasn't said whether or not there will be a fix. It's also unclear how many newer Macs or other PCs are at risk. Regardless of the exact threat, the study isn't very reassuring in an era of widespread surveillance -- if a pair of academics can stealthily record your activity, it's likely that professional spies can do the same.

Microsoft pulls Surface Pro 2 update after reports of battery and installation problems

Microsoft Surface Pro 2 tablet
We hope you weren't quick to leap on the Surface Pro 2 update that popped up last week; if you were, you may be regretting it for a while. The company haspulled the upgrade following reports of both failed installations and battery problems, including a reduced capacity and incomplete charges. A fixed release is coming "after the holidays," but there's no word of an easy way to roll back. Short of resetting the system or a convenient restore point, you may have to live with a buggy tablet for the next few weeks.

Apple Mac Pro starts selling tomorrow

Unveiled back in October, the Mac Pro is starting its retail journey from tomorrow, December 19. Apple redesigned the Mac Pro entirely and has packed it with some of the best hardware you can find around.
Packing a 3.7 GHz quad-core Intel Xeon E5 CPU with Turbo Boost speeds up to 3.9 GHz, the new Mac Pro also has dual AMD FirePro D300 GPUs with 2GB of VRAM each. RAM is 12GB, while storage is 256GB of PCIe-based flash memory. This configuration is the cheapest of them all and comes for $2,999.
You can order the Mac Pro with a 3.5 GHz 6-core Intel Xeon E5 CPU, 16GB of RAM and the same 256GB storage for $1000 more at $3,999. Apple also offers a more powerful 8-core or 12-core Intel Xeon E5 processors with 6GB AMD FirePro D700 GPUs and up to 64GB of RAM and 1TB of flash storage.
Apple boasts that all units are assembled in the US. The futuristic casing of the new Mac Pro offers great connectivity with dual Ethernet ports, HDMI, six Thunderbolt 2 ports, Bluetooth 4.0, Wi-Fi 802.11ac and four USB 3.0 ports.

Nokia Lumia 2520 new advertisement

Nokia UK has posted a new ad for the Lumia 2520 tablet. There’s no running away from the fact that it’s kind of strange and is up for the viewer’s interpretation.
It portrays a man that wants to get a new haircut entering a barbershop and instead of a professional barber, he gets his hair cut by him tapping the Lumia 2520. It’s weird, I know, but check out the ad for yourself below.
In the previous ad of the Nokia Lumia 2520, the Finns mocked the iPad for it not coming with a full Office suite. While this may have helped Nokia’s first slate gather some attention, we don’t think this last ad will do quite as well.
The Nokia Lumia 2520 launched on AT&T on November 22 for $399 with a two-year contract. In case carrier contracts aren’t your thing, you can get it straight from Nokia for $499. That’s just $50 more than the Microsoft’s Surface 2, which lacks 3G/LTE connectivity. In the UK, the Lumia 2520 will be exclusivelyoffered by John Lewis for £399.99.

LG announces 4K UltraWide monitor line-up

LG has officially announced its new UltraWide 4K family of monitors, which currently consists of three members – 29″, 31″ and the 34″ flagship.
The 29″ (29UM95) and the 34″ (34UM95) will pack a 3,440 x 1,440 pixel resolution and a 21:9 aspect ratio. LG claims they support 99% of the sRGB gamut and will include its True Color calibration software for free. The 31″ (31MU95) is a bit different, as its IPS panel packs a higher resolution at 4,096 x 2,160 pixels at a 19:10 aspect ratio. More specifically, it’s a DCI (Real 4K) IPS panel, which supports the higher pixel density.
The 31MU95 will also sport two 20Gbps Thunderbolt ports, which LG says will allow you to watch 4K footage and back it up while doing so. The 31″ also sports the same resolution as the footage recorded by the 4K RED Epic and Scarlet cameras, which means no black bars while watching movies shot with those.
Pricing and availability haven’t been announced, but LG is planning to showcase all the displays at their CES 2014 booth. We can only guesstimate how much LG will ask for its monitors, but having in mind thatASUS prices its 4K monitor at $4000, cheap isn’t what will describe them.

Windows Phone Store reaches 200,000 apps

The continued efforts from Microsoft is paying off as the Windows Phone Store hit 200,000 apps just a few days ago. From modest beginnings in 2010, to 100,000 apps in June last year to double that just in time for the holidays this year.
Microsoft will be releasing $100 million worth of gift cards to 100 retailers across 41 markets to make it easier for users to buy apps (i.e. receive a gift card for the holidays).
Microsoft is stepping up its game when it comes to carrier billing. In developing markets where credit cards are rare, carrier billing brings a 6-fold increase in app purchases. Just recently Microsoft finalized agreements with new carriers, bringing the total to 51 carriers across 31 markets, more than any other platform.
The Windows Phone Store is available in 190 countries, offering 200,000 apps and serving 12 million requests each day. That’s not a billion like the Google Play Store and Apple App Store, but Microsoft’s store has already covered the majority of the key apps.

LG Chromebase all-in-one desktop goes official with 21 inch display and Chrome OS

LG unveiled the Chromebase – an all-in-one 21” desktop running Google’s feather-light Chrome OS. The device will be showcased next month, during CES 2014 in Las Vegas.
The LG Chromebase is powered by Intel’s fourth generation Celeron CPU. The display is a 21” Full HD IPS unit which can double as an external monitor via a dedicated HDMI port.
The Chromebase packs 2GB of RAM and 16GB of built-in memory, as well as a 1.3MP camera for video calls. In addition to the abovementioned HDMI port, the device features a trio of USB 2.0 ports and one USB 3.0 port. LG’s available accessories for the desktop will include a keyboard, a mouse, and a cable organizer.
There’s no word on pricing or availability of the LG Chromebase. We’ll find out more about the device next month in Vegas.

Oppo confirms the Find 7 will have a 2K screen

The upcoming Oppo Find 7 is rumored to have a lot of cool specs, among which a 2K screen that's as big as 5.7". Oppo officially denied that the Find 7 will have a 5.7" screen (or a 7" one for that matter), but now the company is confirming the 2K resolution.
The 2K resolution in question (there are several) is probably QHD – no, not qHD, QHD or Quad HD (4x 720p). That's 2,560 x 1,440.
Other rumored specs include a Snapdragon 805 chipset and 3GB RAM to handle the massive resolution. Despite the several official confirmations from Oppo, the company is yet to announce when the Find 7 will be unveiled.

Oppo missed the opportunity to launch the first 1080p phone (despite what the tweet says, HTC beat it with the Butterfly by a month) and now history might repeat itself – Vivo is planning to unveil the Xplay 3S with a 5.5" QHD screen tomorrow (unless there's yet another delay). Of course, it doesn’t matter which company announces first but which one brings a real device to the market, so Oppo still has a chance.

Cornell 3D prints a working speaker -- coils, magnets and all


From the sound of it, it's not a very good speaker. But then, that's not quite the point. What's particularly cool there is that a team of Cornell researchers created the whole thing using 3D printers -- the plastic shell and conductive and magnetic pieces. The speaker marks a step toward a larger utopian vision where entire products are fabricated using such techniques, not simply shells and other miscellany. That's still a ways off, of course. Aside from the clear (or not so clear) sound issues, there are some roadblocks. For one thing, there's the fact that the job still required two separate printers for different components. Also, the speaker had to be hooked up to wires to play the audio clip of President Barack Obama name-checking 3D printing. Still, it's easy to see in the short clip below where things may be going.

Clack-Clack FACE gives a typewriter new life as a text-based portrait painter

Clack-Clack FACE gives a typewriter new life as a text-based portrait painter
There's something oddly romantic about taking a piece of archaic technology and giving it new life as a work of 21st century art. Take the Royal Empress typewriteryou see above. This particular model was built in 1961 and eventually landed in the hands of Amanda Gelb as graduation gift. She and her fellow classmates, Jinyi Fu and Quingyuan Chen, looked at the hunk of aging metal and saw potentialinstead of an obsolete writing tool. For their installation at the ITP Winter Show, they wired up each of the keys to an Arduino for tracking what a user types, then paired that with a tiny projector that displays the letters on a sheet of paper wrapped around the platen.
The "face" part of the equation comes from the webcam mounted to the top of the typewriter case. It uses brightness to map a silhouette of the person sitting in front of it and fills only the darkened areas with letters, creating an ASCII portrait in real time. The code also automatically loops the letters you type, so even if you press only a single key the picture will appear. Of course, you could also type out a love letter or a quick blog post and the whole thing will be wrapped inside the confines of your outline. When you're done, you can press the re-labeled print key and a laser printer spits out your portrait.
While there are already plenty of apps and sites out there that will automatically create ASCII versions of images, there's something alluring about sitting in front of gorgeous piece of hardware and creating it live. Plus, there are few things in this world as satisfying as pressing down the stiff keys of an old typewriter, hearing the titular onomatopoeia and seeing the letter appear before you. Especially when youknow you're creating a work of art, even if you're a terrible writer.

Dell Venue 8 Pro review: a good Windows tablet, but wait for the bug fixes

Dell Venue 8 Pro review: a good Windows tablet, but wait for the bug fixes
And then there were... four? Once considered a novelty, 8-inch Windows tablets are now everywhere: Lenovo has one; so does Toshiba; and Acer is already on its second. Not to be left out, Dell recently started shipping the Venue 8 Pro, which costs about the same as its competitors ($300), but adds an active digitizer for pen input (psst: The stylus is sold separately). Like most of its rivals, too, it makes use of a quad-core Intel Atom processor promising fairly long battery life, and enough power to handle some lightweight desktop apps, in addition to whatever you might download from the Windows Store. Unfortunately, we can't really name our favorite 8-inch Windows tablet until we review a few more of them, but for now, we can safely say the Venue 8 Pro offers some decent value for the money. Read on to see why.

HARDWARE

SONY DSC
We know, we know: Looks aren't everything. But to the extent that good design and build quality matter (especially on budget devices like these), Dell is off to a fine start. Unlike its rivals, which mostly have plain plastic backs, the Venue 8 Pro is coated in a soft, rubbery finish (available in black and red) that makes the device easier to grip and also lends it a premium feel -- not unlike how we felt about the rubber back on the original Nexus 7. Be warned, though, that while the textured back cover does a good job masking fingerprints, it is susceptible to scratches. Granted, you probably won't ding it up just by putting it in a bag with other items, but at one point, I accidentally scraped it with the micro-USB cable while attempting to plug in the device. It's a faint mark, but still, I can't unsee it. At least the glass on the front side seems pretty scratch-resistant.
You'll be hard-pressed to find an 8-inch tablet that isn't thin, light and easy to hold in one hand. Nonetheless, all that's true of the Venue 8 Pro: It immediately makes a good case for choosing an 8-inch tablet over a 10- or 11-inch one. According to our own Sean Buckley, who owns one, it's even small enough to fit in the back pocket of his (not-too-skinny) jeans. As it happens, though, it's even more compact than some rival models. All told, the tablet weighs in at 0.87 pound and measures 0.35 inch thick, leaving just enough room on the edges for you to comfortably rest your fingers. The Acer Iconia W4, meanwhile, weighs 0.91 pound and measures 0.42 inch thick; Toshiba's Encore tablet also nears the one-pound mark, landing at 0.98 pounds. Point being: You can't do much better than the Venue 8 Pro, at least as far as portability goes.
SONY DSC
One thing that makes the Venue 8 Pro a bit strange to use at first: It appears to be missing a Start button. More precisely, it has one; it's just not where you'd expect it to be. Instead of a touch-sensitive Start button built into one of the bezels, the tablet has a physical Start key located on the top portrait edge of the device. We'll be honest, it took us a little while to stop tapping the bezels and go straight for the physical button. That said, now that we've gotten the hang of it, we have to give Dell credit for at least choosing the button location carefully. Since the key sits on the top edge, over toward the right, it's easy to hit when you're using the tablet in portrait mode, and also when you flip it over into landscape, at which point the button is within reach of your left thumb. Still, a capacitive key would've been even easier. Will you do that for us next time, Dell? At least consider it?
Continuing our tour of the hardware, you'll find most of the usual suspects: a headphone jack up top, with a micro-USB charging port, power/lock button and volume rocker on the right portrait side. There, you'll also find a covered microSD slot to augment the 32GB or 64GB of built-in storage. And yes, you probably will want to insert a memory card -- after installing a bunch of games and 10 gigabytes of comics, we burned through 64GB alarmingly quickly. One thing you won't find: a micro-HDMI port. That's a shame if you ever feel like pushing your HD content to a bigger screen (N.B.: This does support the Miracast wireless streaming standard, but it's not fair to expect that everyone's TV will be compatible). Meanwhile, other 8-inch tablets like the Toshiba Encore do offer this, so if mirroring your apps on a big screen is a priority, you at least know where to look.
SONY DSC
The left side of the tablet is blank, and on the bottom, you'll find the lone speaker. That means if you're cradling the tablet in portrait mode while listening to music, the speaker grille will stand free and clear of your hands. But if you're holding it in landscape, there's a good chance your right hand will cover it. No matter, though: This speaker is gloriously, shockingly loud -- far louder than we'd expect a single speaker on a mobile device to be. Be warned, however, that the sound quality gets distorted at top volume, and the difference is especially stark if you're used to stereo sound on devices like the HTC One. At any rate, if you're listening to '80s hair metal, you'll want to take it down a notch to really appreciate the song.
Finishing up, there's a 5-megapixel camera around back, along with some "Intel Inside" branding and the usual FCC label, which can be a bit difficult to peel off. The 1.2MP webcam, meanwhile, is located on the front bezel, over toward the right corner.

ETC.

SONY DSC
For $300, Dell is selling the Venue 8 Pro as a standalone slate, but we also thought we'd walk you through the accessories too -- you know, just in case you want to sometimes use the device as a pint-size laptop replacement. For starters, there's the $40 folio case, which has a tough shell and a soft suede-like lining. You can use it as a straight-up case, of course, but you can also fold it up, allowing you to watch movies with the screen propped up. There's also a second position, with the tablet lying face-up at a slight angle, making on-screen typing just a bit easier.
In our experience, we found the tablet stays put once you prop it all the way up, though it can be quite difficult to pry out of the case when you feel like going commando. (On the plus side, this means you don't have to worry about it falling out.) And what if you want to do some typing? Well, Dell has also announced a wireless keyboard, but it's not shipping yet and indeed, we haven't had a chance to try it.

DISPLAY

SONY DSC
Given that the same Bay Trail processor powers all these 8-inch Windows tablets, there aren't many opportunities for companies to differentiate themselves: It's design, display quality and maybe camera performance. And... that's it. Fortunately, Dell didn't skimp on the screen -- the 1,280 x 800 IPS panel here is just lovely. The problem is, though the screen is rated at 400 nits, you'll rarely see the screen get that bright, at least not with auto-brightness turned on; for whatever reason, the tablet defaults to a very dim setting, and even if you manually adjust the brightness slider, you still can't go any brighter.
Fortunately, Dell says it's working on a firmware fix so that when you do use the ambient light sensor, the screen won't default to such a conservative setting. For now, unless you happen to be working in a dimly lit room, you'll want to turn off the ambient light sensor, even if it means a dip in battery life. Plus, even with the brightness at a more medium setting, colors are punchy, without being too saturated, and the screen is easy to view from various angles. So it is quite possible to enjoy the vibrant screen while still getting long battery life.
Dell surprised all of us when it announced the Venue 8 Pro with an active digitizer. Most 8-inch Windows tablets (heck, most budget tablets) don't support pen input. Here, though, you get a Synaptics digitizer built in, even on the base $300 model. It's a shame, then, that it doesn't work nearly as well as the pen displays you'll find on the Surface Pro 2 or any of the Galaxy Note tablets. In desktop mode, we were initially tickled by the pen's hovering capabilities, but our enthusiasm waned quickly after that. Sometimes, we had to try multiple attempts to launch a desktop program by double-tapping the shortcut with the pen. Other times, when using Explorer, the pen didn't initially highlight the object we wanted it to, or we would see stuttering as we tried to scroll through a long file list. So far, Dell has already issued at least one firmware update meant to address this problem, and it's also promising another fix that should hopefully make pen input even smoother.

SOFTWARE

SONY DSC
In retrospect, it's not surprising that Microsoft decided to showcase Windows 8.1 on 8-inch tablets: Many of the improvements to the OS make it especially easy to use on smaller-screened devices. For example, new keyboard shortcuts allow you to swipe the space bar to cycle through spelling suggestions, and to swipe various letters to expose the punctuation symbols that would otherwise be hidden. Also, you get more options for Live Tile sizes, including an extra small one that seems especially well-suited to smaller displays like this.
Additionally, all of the other headline features in Windows 8.1 can be found here, including an always-visible Start button in the lower-left corner of the desktop, expanded split-screen options and the ability to take photos from the lock screen (an especially handy feature on a smaller device like this). Also, as you've no doubt heard by now, Windows 8.1 ushers in a slew of new first-party apps, including Reading List (an alternative to Pocket), Bing Food & Drink, Bing Health & Fitness, a calculator, an alarms app and a sound recorder. Meanwhile, other built-in programs have received meaningful updates, with Xbox Radio and a new set of photo-editing tools, to name just two examples.
And what of third-party apps? We're happy to report the selection is steadily growing, even if there are still some holes. Flipboard recently arrived on the Windows Store recently, as has SlingPlayer, which launched as we were writing this review. Even before that, we had apps like Facebook, Twitter, Foursquare, Pandora, Rhapsody, Slacker Radio, Amazon Kindle, Nook, Zinio, Angry BirdsBejeweled, Fitbit, Mint.com, NYTimes, Wall Street Journal, Hulu Plus, Netflix, ESPN, ABC Family, ABC News, NBC News, CBS, CBS Sports, CNN, MTV and the AP.
At this point, the ol' "Windows doesn't have enough apps" argument simply doesn't carry as much weight: The Windows Store catalog is growing, and it's growing fast. That said, if you buy the Venue 8 Pro (or any other Windows tablet), you still won't find every program you're searching for, at least not on the day you buy it. Some notable omissions? Instagram, Tumblr, HBO Go, Pocket and a first-party NPR player, to name just a few. Some major airline apps would be nice, too. Again, though, given how many heavy-hitters eventually made their way onto the platform, we have faith that most of these holdouts will join the fold at some point or another.

PERFORMANCE AND BATTERY LIFE

DEVICEPCMARK73DMARK063DMARK11ATTO (TOP DISK SPEEDS)
ASUS Transformer Book T100 (1.33GHz Intel Atom Z3740, Intel HD graphics)2,4612,113E338 / P209123 MB/s (reads); 58 MB/s (writes)
Dell Venue 8 Pro (1.33GHz Intel Atom Z3740D, Intel HD graphics)2,3431,986E299 / P16486 MB/s (reads); 45 MB/s (writes)
As we already discovered when we reviewed the ASUS Transformer Book T100, Intel's new Bay Trail processors are powerful enough to handle not just Windows Store apps, but also lightweight desktop programs like iTunes, Spotify and HipChat. That's true here as well: The Venue 8 Pro is fit to run all the above programs, along with Microsoft Office and even some games, as we'll describe in a moment. On the Metro Modern UI side, the Venue 8 Pro flies through animations and transitions, and opens apps quickly. It's worth noting that the processor used here, the Atom Z3740D, has a slightly lower clock speed than the Z3470 used in other tablets (1.83GHz max vs. 1.86GHz), along with less RAM support (up to 2GB, rather than 4GB). That said, you might not notice the difference, aside from benchmark scores.
Like the T100, it takes 11 seconds to boot up -- about half the time it takes the Surface 2 to fully load. Even more than that, though, the Venue 8 Pro's biggest talent might actually be web browsing: Pages load quickly and jumping between tabs is a breeze. If benchmarks mean anything to you, it notched a score of 405ms in the SunSpider JavaScript test. Remember, too, that lower numbers are better, so this actually surpasses the T100 (461ms) and falls right in line with the Surface 2 (406ms). Unfortunately, the Samsung-made SSD can't lay claim to such speed: It fails to break write speeds of 100 MB/s and its read speeds of 45 MB/s are even lower than what we achieved on the T100.
As for gaming, the Dell Venue 8 Pro's touch-only interface doesn't lend itself well to traditional titles, but its Bay Trail processor can run more than Windows 8 apps. Even so, don't expect it to replace your gaming rig: With few exceptions, the Venue 8 Pro stuttered heavily in most 3D-rendered games. Battlefield 3 andBioShock Infinite never stood a chance of being playable, but older games flourish. Games like The Elder Scrolls III: Morrowind ran without a hitch, and even Half-Life 2chugged along at a steady 40 fps with low/medium details. Newer games can be coaxed into running, but they won't be usable: Skyrim, for instance, struggled to maintain 15 fps. Stick to older PC games (or the Windows 8 Store) and you'll be fine. Oh, and heads-up: During gaming and other intensive tasks, the tablet gets warm enough that you can feel the heat even through the folio case. If you're just surfing the web, though, you can expect the tablet to stay cool.
It's also worth noting that Civilization is playable as a purely touch-based game, as it's one of the only modern PC games that has a control mode designed specifically for tablets. It does stutter a little, but it works well enough to play, and even that's notable. After all, with the exception of Civilization, you won't get past simply "running" many games without peripherals to actually play them.

Dell specifically claims that the Venue 8 Pro's battery can last up to 9.9 hours (that's nine hours and 54 minutes, for all you lazy mathematicians out there). Perhaps with light usage, you can get the tablet to last that long, but in our video-looping test, we managed a more modest seven hours and 19 minutes. Then again, that was with the brightness fixed at 50 percent. With the ambient light sensor kept on, we got eight hours and 40 minutes of continuous video playback -- a much better showing, we'd say. So, with auto-brightness turned on and a more modest task load, we can see getting closer to 10 hours, for sure.
As for how this compares to other 8-inch Windows tablets, well, that remains to be seen -- we unfortunately haven't reviewed any competing products yet, so it's tough to say if seven hours and change on our specific test is good or bad. Either way, you should expect to charge this thing roughly once a day: Though the battery life is impressive, the standby time isn't great.

CONFIGURATION OPTIONS

The Venue 8 Pro starts at $300 with 32GB of built-in storage and the same internals we mentioned earlier: a 1.33GHz Intel Atom Z3740D processor, Intel HD graphics and 2GB of RAM. If you want that folio case, you'll need to step up to the $340 model, which also comes with 32GB of storage. Add $30 on top of that (bringing the price to $370) and you get the case and stylus. For $390, you can get the case and the wireless keyboard we mentioned earlier. Across the board, you can also get 64GB of storage instead of 32 gigs; just be prepared to tack on an extra $50 to the total price.
Oh, another heads-up: The case comes in both red and black, though as of this writing, the spunky red version is on backorder until December 25th.

THE COMPETITION

SONY DSC
Remember when the Acer Iconia W3 came out and we gave a pass to most of its shortcomings because it was so reasonably priced? (And was the only 8-inch Windows 8 tablet.) How quaint, right? Today, the Dell Venue 8 Pro is one of several 8-inch Win 8 tablets, and for the record, they're all affordable. Starting with Acer (since we already name-checked it), the company has replaced the Iconia W3 with the W4, which brings a higher-quality panel with better viewing angles (the 1,280 x 800 resolution is the same, though). In addition, it's thinner and lighter than before, and makes use of a new Bay Trail processor -- as do all the tablets we're about to mention here. That retails for $330 and up, with the keyboard accessory sold separately. Only problem? It doesn't seem to be shipping yet. Womp womp.
Next up: the Toshiba Encore, the company's first 8-inch Windows tablet. If we go by specs and price alone, it's near-identical to the W4: 1,280 x 800 display, quad-core Bay Trail processor, a 2-megapixel front-facing camera and a price of $330 (available now). The only obvious difference? The rear camera shoots at 8 megapixels, not 5. Otherwise, we can't vouch for performance or battery life right now, since we haven't reviewed it yet. But do keep it in mind as you're shopping; it's clearly in the same class as all these other devices.
Ditto for the Miix 2 from Lenovo. This, too, has an 8-inch 1,280 x 800 display, a quad-core Intel Atom processor and dual 5MP/2MP cameras. Unlike the others, though, it's priced at an especially low $299. We haven't reviewed it yet, though, so we can't compare the performance right now.

WRAP-UP

SONY DSC

Then again, we expect most of its rivals do too, given that they also make use of Intel's low-power Bay Trail chips. For the time being, it appears Dell might have won in the display department, thanks to that high brightness rating and also its ability to accept pen input (imperfect pen performance is better than none, we say, especially given that a fix is coming, and that very few budget tablets even offer this feature). On the other hand, the omission of a micro-HDMI port is odd, as is Dell's refusal to add a capacitive Start button. All things considered, we suspect the Venue 8 Pro can still hold its own against other 8-inch Windows tablets, but don't quote us on that until we test more of them. For now, though, it's clear the Venue 8 Pro offers a good deal of value for $300, and that its benefits ultimately outweigh its quirks.Should you buy the Venue 8 Pro? The answer isn't exactly "yes," and it isn't exactly "no." It's "wait." Wait for Dell to issue some firmware updates to address the aggressive auto-brightness settings and the flaky pen performance. And wait for more of these 8-inch Windows tablets to start shipping. It's easy to say that the Venue 8 Pro offers decent value for the money: You get a vibrant, 400-nit tablet display, long battery life and a processor powerful enough to run lightweight desktop apps when you need them.

Windows Phone 8.1 reportedly getting a Notification Center and personal assistant

With each new update, Microsoft's Windows Phone platform resolves more andmore concerns that we've had ever since its initial launch three years ago. According to Tom Warren at The Verge, Microsoft has a new update in the works -- currently known to us as Windows Phone 8.1 -- that will implement a new Notification Center as well as a personal assistant that will be closer to Google Now and Apple's Siri technology. This new version of Windows Phone will reportedly be revealed at the company's BUILD conference in April.
So how exactly will the new Windows Phone Notification Center work? According to Warren's sources, it'll be accessed the same way iOS and Android users are accustomed to: by swiping down from the top of the screen. Not necessarily the most original idea, but if this is true, it would at least be much more familiar (and perhaps more compelling) to anyone looking to switch to Windows Phone from one of its competing platforms. That's not to say it will be identical, however, as a short swipe would bring up Quick Settings, while a long swipe would display your full history of notifications.
Also, WP8.1 is where Microsoft's Cortana feature would finally come in handy. This will offer much more interaction and personalization than the current Bing Search, in that it will feature more of a contextual learning experience based on location and other personal data. These new features will help make the new WP assistant more competitive with Google Now and Siri.
Finally, Warren mentions a few other features in the works for WP8.1: independent volume controls (ringtone and media would be separated), additional Enterprise support with VPN, Facebook and Twitter support in the People Hub and Bing Smart Search results that bring Windows Phone closer to its desktop counterpart. Xbox Music and Video are also rumored to be separated in the new update. Nokia's also reportedly working on two smartphones that will come out around the same time as 8.1, one of which involves off-the-glass gestures and another one that utilizes virtual navigation buttons.
