jones_supa sends this news from The Verge: "Rumored for a long time, Nokia's Windows tablet has finally been released. Microsoft might be buying Nokia's device business, but for the next few months they're going to be battling it out as competitors for Windows-based tablet market share. The new Lumia 2520 tablet is everything you'd expect from Nokia; it comes with a very bright and colorful full HD 10.1" display and it looks just like a supersized version of a Lumia series Windows Phone. Other Nokia signatures are a high-quality camera and maps which work reliably offline too. Inside there's a 2.2GHz quad-core Snapdragon 800 processor, and the word is that Windows RT 8.1 runs great. It's responsive and multitasking apps seems just as good as the Surface 2. Because this is Windows RT you also get access to the desktop Office apps as part of this device. At that point the real Surface-like keyboard and trackpad become useful, alongside two USB ports. Estimated battery life is of 11 hours, which is increased when the cover is attached."

Today Apple held a press conference to unveil its updated software and hardware products. The biggest news was the announcement of the 'iPad Air,' which has a 9.7" Retina display. It's 7.5 mm thick, which is 20% thinner than the older iPad. The weight has dropped from 1.4 lbs to 1.0 lbs, and it runs on a 64-bit A7 chip with an M7 motion coprocessor. Apple claims performance has doubled over the previous-gen iPad. The iPad Air will be available on November 1st. The iPad Mini is getting a new revision as well. The display has been upgraded to 7.9" at 2048x1536, which is the same resolution as the iPad Air. The new Mini has an A7 chip as well.

Apple also announced that the new version of Mac OS X (10.9 Mavericks) is available now and is free to all Mac OS X users. It includes better multi-monitor support, tabs in Finder, and a number of performance optimizations. The Macbook Pro is getting updates to the 13" and 15" models, which are now running on Intel Haswell processors. They both have PCIe SSDs, 802.11ac Wi-Fi, and Thunderbolt 2 support. Apple also talked about the redesigned Mac Pro line. As you may recall from WWDC, the new model takes up about about 1/8th of the volume as the old one. It's cooled by a single fan, uses 70% less power than the earlier model, and puts out 12 dB of noise when idling. It'll be available in December. On the software side, Apple has been updating a lot of their software to add 64-bit support and mesh with the new iOS 7 style of design. This includes iPhoto, iMovie, and Garageband, as well as the iLife and iWork software suites. iWork is also getting collaborative work features, and it's now free with new Macs and iOS devices.

colinneagle writes "I installed Ubuntu Touch "1.0" on my first-generation Nexus 7 tablet and have been using it as my main tablet system for the last four days. Here's how it went. First off, the installation was surprisingly painless. I followed the official instructions and didn't encounter a single problem. That being said, the installation is really geared toward software developers, power users or people already comfortable on a Linux command line. If you're not in one of those categories, I recommend holding off for the time being. Once installed, Ubuntu Touch booted up rather quickly — in only just a few seconds (a fair bit faster than Android 4.x on the same tablet). And, immediately, I was presented with a short tutorial that appears the first time the system is booted, which, I might add, has got to be one of the slickest, least annoying tutorials I've seen. But... there were problems. The battery life was, to put it mildly, terrible. Performance has been mixed, and the OS was prone to what I call 'The Pulsating Seizure Feature' a few dozen times over the weekend. In a nutshell: launching apps (and, occasionally, moving between apps) can cause the device to freeze and begin flashing the screen rapidly."

MojoKid writes "The LG G2 is the follow-up to LG's Optimus G Pro. It's also one of the few smartphones on the market right now powered by Qualcomm's Snapdragon 800 quad-core SoC. The G2 sports a 5.2-inch 1080p display, 2GB of RAM and up to 32GB of on board storage. However, the 2.26GHz quad-core Snapdragon 800 chip on board also has Qualcomm's Adreno 330 GPU that even gives NVIDIA's Tegra 4 a run for its money in gaming and graphics performance. Though the G2 has a rather unorthodox volume rocker and power button assembly on the back of the phone, once you get used to the location, it's actually a pretty comfortable control system. What's pretty impressive though is the G2's performance combined with its 3000mAh battery that offers a solid balance of horsepower and battery life and rivals flagship phones like the Samsung Galaxy S4 and Apple's iPhone 5S."

New submitter mjone13 writes "Dave Feldman, in a blog posts, says that the problem Android faces is giving consumers too much choice. He cites several studies which state that consumers generally are unhappier when they have too much choice. 'Catering to all individual preferences creates a bloated, bland product. Not to mention a UI that’s impossible to navigate. Furthermore, people are notoriously bad at identifying what we want. And what we do want is influenced heavily by what we know — our expectations are constrained by our experience.' He then goes on to talk about Android fragmentation, app developer problems and bug issues. Finally he says the people who general prefer the choice Android provides are tinkers similar to gear heads who love tinkering with their car. 'I think many who extol Android’s flexibility fall into the tinkerer category, including some tech bloggers. They love all the ways they can customize their phones, not because they’re seeking some perfect setup, but because they can swap in a new launcher every week. That’s fun for them; but they’ve made the mistake of not understanding how their motivation differs from the rest of us.' Is choice really a problem for Android?" Whether it's a problem depends on what the goals are. Providing a satisfying experience to a bunch of tinkerers is a very different thing from providing a satisfying experience to the multitude of non-tinkerers who buy smartphones.

MojoKid writes "It's been a long time since many have seen a dreaded 'blue screen of death' (BSoD), but it's back and in the most unlikeliest of places. Oddly enough, some Apple iPhone 5S owners are reporting BSoD errors, though they're a little different from the ones you may remember seeing on Windows desktops. Rather than spit out an obscure error code with a generic description, some iPhone 5S devices are suddenly turning blue before automatically restarting. The Numbers app in Apple's iWork suite, a free program with new iPhones, seems to be the primary cause, though BSoD behavior has also been observed in other applications, according to complaints in Apple's support forum."

An anonymous reader writes "SFGate reports that Stanford researchers have figured out a way to generate a unique fingerprint from a cell phone's suite of built-in sensors. The tiny accelerometers, gyroscopes, microphones, and speakers in cell phones have characteristics that vary slightly from handset to handset, and these variations may contain enough information to uniquely identify a given handset. How that information might get from the phone to a third party varies (the article describes a JavaScript snippet reading the Z-axis accelerometer, though it says little about how the user might block such information from being read), but the possibility for abuse is certainly troubling."

Nate the greatest writes "Guilford County Schools' headline grabbing tablet program is back in the news again. The program came to an abrupt end last Friday when the school district announced that they were recalling all of the Amplify tablets. GCS had leased over 15 thousand of the tablets (at a cost of $200 a year) for its middle school students, but decided to recall the tablets just one month into the school year after some 1500 students reported a broken screen. Around two thousand complained of improperly fitting cases, and there were also 175 reports of malfunctioning power supplies. There's currently no explanation for the cases or power supplies, but GCS has stated that the tablets broke because they lacked a layer of Gorilla Glass. This was listed in the contract, but the school district did not confirm the condition of the tablets before accepting them. This program was the poster child for News Corp.'s entry into the educational market. It was the single largest program to use the Amplify tablet, and its failure represents a serious setback. The Amplify tablet now has a record for poor construction quality and a breakage rate that is 12 times higher than what Squaretrade reported in early 2012 for the iPad 2."

Features of Google's next Nexus phone have finally been outed, along with confirmation that the phone will be built by LG, as a result of a leaked service manual draft; here are some of the details as described at TechCrunch: "The new Nexus will likely be available in 16 or 32GB variants, and will feature an LTE radio and an 8-megapixel rear camera with optical image stabilization (there’s no mention of that crazy Nikon tech, though). NFC, wireless charging, and that lovely little notification light are back, too, but don’t expect a huge boost in longevity — it’s going to pack a sealed 2,300mAh battery, up slightly from the 2100mAh cell that powered last year’s Nexus 4. That spec sheet should sound familiar to people who took notice of what happened with the Nexus 4. Just as that device was built from the foundation laid by the LG Optimus G, the Nexus 5 (or whatever it’s going to be called) seems like a mildly revamped version of LG’s G2."

Microsoft made some confident sounding claims about sales of its first-generation Surface tablets before it became clear that the tablets weren't actually selling very well. So make what you will of the company's claim that the second version is "close to selling out." As the linked article points out, the company has "fallen short of offering any real explanation as to just how “close” to selling out the Surface 2 and Pro 2 really are – nor have they indicated how many were on hand to order in the first place."

quantr draws your attention to a Bloomberg report that Microsoft has reached out to HTC to see if the company would be interested in adding Windows as a second OS to its Android handsets. From the Bloomberg story: "Its willingness to add Windows as a second operating system underscores the lengths to which Microsoft will go to get manufacturers to carry its software. HTC, the first company to make both Windows and Android phones, hasn’t unveiled a new Windows-based handset since June and has no current plans to release any more, said one person. Microsoft, with 3.7 percent of the market, is finding it necessary to make concessions after agreeing to acquire Nokia Oyj’s handset unit, which competes with other smartphone makers. [Microsoft operating systems head Terry] Myerson was planning to visit Asia this month and meet with senior executives at Taoyuan, Taiwan-based HTC to discuss his proposal, one of the people said."

An anonymous reader writes "After Samsung got caught out cheating on benchmarks (Note 3, Galaxy S4) AnandTech has done a detailed analysis of the state of benchmark cheating amongst Android OEMs. With the exception of Motorola, literally every single OEM they've looked at ships (or has shipped) at least one device that does benchmark-specific CPU optimizations. AnandTech also thinks it will get worse before it gets better. 'The hilarious part of all of this is we’re still talking about small gains in performance. The impact on our CPU tests is 0 - 5%, and somewhere south of 10% on our GPU benchmarks as far as we can tell. I can't stress enough that it would be far less painful for the OEMs to just stop this nonsense and instead demand better performance/power efficiency from their silicon vendors.' The article notes that Apple doesn't do any of the frequency gaming stuff."

tlhIngan writes "A few months ago, Samsung was caught gaming benchmarks on the Galaxy S4 (International version). They would lock the GPU at a higher-than-normal frequency when certain applications were run, including many popular Android benchmarking programs. These had the expected result of boosting the performance numbers. This time, the Galaxy Note 3 was caught doing the same thing, boosting CPU scores by 20% over the otherwise identical LG G2 (which uses the same SoC at the same clock). Samsung defends these claims by saying the other apps make use of such functionality, but Ars reversed-engineered the relevant code and discovered it applied only to benchmark applications. Even more damning was that the Note 3 was still faster than the G2 when run using 'stealth' (basically renamed) versions of the benchmarking apps which did not get the boost."

mikejuk writes "We all do it — place our phones down on the desk next to the keyboard. This might not be such a good idea if you want to keep your work to yourself. A team of researchers from MIT and the Georgia Institute of Technology have provided proof of concept for logging keystrokes using nothing but the sensors inside a smartphone — an iPhone 4 to be precise, as the iPhone 3GS wasn't up to it. A pair of neural networks were trained to recognize which keys were being pressed just based on the vibration — and it was remarkably good at it for such a small device. There have been systems that read the keys by listening but this is the first system that can hide in mobile phone malware."

dryriver writes "We've seen real laser guns before pulling off tricks like starting small fires, or popping black balloons. That's cool, sure, but it's got nothing—on this handheld laser rifle. Developed by TWI this laser-cutter was initially designed for use by robots, but a few recent tweaks including a pistol-grip and a trigger made it into a human-sized rifle. It is designed specifically with nuclear decommission in mind, specifically chopping up huge pieces of metal infrastructure into bite-sized bits that are easily disposed of. And while it's definitely suited for that, it has some short-comings compared typical rifles. That range is pretty low, for instance, and it's not exactly mobile."

KentuckyFC writes "The remarkable growth of mobile phone use is transforming many parts of Africa. In Sudan and Gabon, more than half of all adults use their phones to transfer money, the activist website Ushahidi used text messages to map post-election violence in Kenya in 2008 and in Nigeria, mobile music services are a multi-million dollar industry. Now demographers have used the way people purchase airtime to map wealth in Cote d'Ivoire on Africa's west coast. They analysed a dataset from one of the country's largest mobile operators containing caller IDs, the cell towers used for each call and the time and amount of all airtime purchases. The researchers say an individual's airtime buying habits are a good proxy for his or her income. As a result, they were able to to map wealth across the entire country. Their map clearly shows the wealthy cities such as Abidjan, the largest seaport in West Africa. But it also shows an unexpectedly wealthy region in the conflict-ridden area that borders Liberia. This wealth probably arises from illegal activities on the border, such as drug, arms and human trafficking, they conclude."

colinneagle writes "Members of an FAA advisory panel are reportedly meeting this week to make changes to the ban on the use of electronic devices on an airplane during takeoff and landing. The new regulations will allow the use of electronic devices to access content stored on the devices, including e-books, music, podcasts, and video. Sending emails, connecting to Wi-Fi, and making phone calls will still be prohibited. The announcement is expected to be made later this month, and the rules put into effect next year, according to the report."

Dputiger writes "Microsoft has unveiled both the Surface 2 and Surface 2 Pro, updating the former with a Tegra 4 processor and the latter with a new Haswell chip. Among the additional improvements are a more comfortable kickstand with two height settings, 1080p displays for both devices, USB 3.0 support, better battery life, and a higher resolution camera. Pricing for the 32GB Surface without a Touch or Type Cover is set at $449."

MTorrice writes "By attaching a lightweight, inexpensive device to the back of a smart phone, scientists can convert the phone into a sensitive fluorescence microscope. The attachment [paper abstract] allows the phone's camera to take pictures of single nanoparticles and viruses, possibly providing a portable diagnostic tool for health care workers in developing countries. For example, doctors in remote regions could use the technique to measure HIV viral loads in patients' blood samples, allowing the doctors to easily monitor disease progression and determine the best course of treatment."

crookedvulture writes "Nvidia has already produced a gaming handheld based on its quad-core Tegra 4 SoC. Today, the company announced plans to build a 7" Tegra Note tablet that uses the same chip. Rather than selling the tablet itself, Nvidia will make the device available through parters like EVGA and PNY. Asking price: $199. That seems a little steep given the Tegra Note's 1280x800 display resolution, which delivers a much lower PPI than the 1080p panel in the latest Nexus 7. But the Tegra Note does have some perks, including front-facing speakers, Micro HDMI output, microSD expansion, and an optional stylus. The tablet also boasts a fancy camera that taps into the Tegra chip's photography engine. Nvidia promises to keep the device updated with the latest versions of Android, too. You can expect to see the Tegra Note for sale worldwide in the next few months."
