Looks like claims that Google's first 10-inch tablet could be an "iPad killer" were warranted: The Google, Samsung Nexus 10 tablet has sold out in the U.K. In the Google Play store, both the 16GB and 32GB Nexus 10 models are now showing as sold out just 24 hours after the tablet went on sale.

There's no word when Google will be receiving its next batch of the Samsung tablets either, as the page simply states, "We are out of inventory. Please check back soon."

Google's 3G enabled Nexus 7 that also went on sale Nov. 13 is also showing as sold out on the Google Play store, despite costing more than the Wi-Fi-only tablet models, according to The Inquirer.

Google Nexus 10

Perhaps the most hyped device in Google's new lineup, many view the Nexus 10 as the first device with legitimate potential to become an "iPad killer."

"Nexus 10 is the ultimate tablet for watching movies or reading magazines. We wanted to build a premium entertainment device, so we partnered with Samsung to do just that," Google said in its recent product announcement on the company's blog.

"Nexus 10 is the highest resolution tablet on the planet with a 10.055-inch display at 2560-by-1600 (300ppi), that's over 4 million pixels right in your hands. It comes with a powerful battery that will get you up to nine hours of video playback and more than 500 hours of standby time. With a set of front-facing stereo speakers, you can watch movies right from your Nexus 10 and they simply sound awesome. But what makes Nexus 10 unique is that it's the first truly shareable tablet. With Android 4.2, you can add multiple users and switch between them instantly right from the lockscreen.

"We believe that everyone should have quick and easy access to their own stuff -- email, apps, bookmarks, and more. That way, everyone can have their own home screens, their own music, and even their own high scores."

The Google ad Samsung Nexus 10, will have the highest pixel density of any tablet on the market, and will be released in the first half of 2013, according to CNET.

Google's Nexus 10 tablet will have a 2,560x1,600 pixel density, which CNET says will "push the display manufacturing tech envelope." That high of a pixel density would place the Nexus 10 at the top of the heap with a higher count than Amazon's 8.9-inch display Kindle Fire HD and Apple's 9.7-inch display iPad 3. It's also higher than the rumored screen specs we've been seeing for Microsoft's 10.1-inch Surface tablets.

"By stuffing that density into a 10-inch screen, the PPI jumps to just shy of 300," says CNET.

The Google, Samsung Nexus 10 also features micro USB and micro HDMI ports, a clear advantage over Apple's iPad 4, which has neither.

As early reviews roll in, the Nexus 10 is scoring some of the highest marks yet for Android tablets. Users have really responded to Google's claims of the device's unparalleled display quality and fawned over the Nexus 10's operating system. One big draw back everyone seems to agree on though is the tremendous lack of third-party apps for the device.

"What remains extremely disappointing - and prevents the Nexus 10 from truly being the iPad's peer - is the paucity of third-party software to shine on this tablet. Google Play has plenty of apps, but too few of them are designed with a roomy tablet screen in mind," said Time in its review.

For its part, Google is hoping the mere existence of the Nexus 10 will persuade developers to begin creating more Android tablet optimized apps.

"Part of the reason why we've invested significantly in building [the Nexus 10] is exactly so that we have more and more motivation for the developer community," Hugo Barra, director of product management for Android, told the Verge.

The lack of apps is one of the biggest features holding back Android tablets from wider market appeal and permeation, a similar set issues currently facig Microsoft with its Surface RT.

Google, LG Nexus 4

Just minutes after going on sale in the U.S., the new Nexus 4 smartphone from Google and LG was already sold out. Visitors to the Google Play store are greeted with a "coming soon" notice for both the 8 GB and 16 GB of the device. It's unclear how many units Google was able to produce by launch time; the company has not commented.

Google releases only one Nexus-branded handset per year. It is meant to serve as the developer device for its Android smartphone platform. The device went on sale first in Australia, where it sold out in mere hours. Later, the Nexus 4 hit the Play Store in the U.K., where it also sold out in about an hour.

The LG Nexus 4 smartphone features a quad-core processor, "which means its super fast," says Google. The phone's display is a "crisp" 4.7-inches (320 ppi) "that's perfect for looking at photos and watching YouTube." The phone offers wireless charging, so, you just have to set the phone down on a power mat to recharge the Nexus 4's battery.

"While Nexus 4 is incredibly powerful under the hood, it also features the latest version of Jelly Bean, Android 4.2-the simplest and smartest version of Android yet," the company said in its statement.

"Starting with the camera, we've reinvented the photo experience with Photo Sphere, which lets you capture images that are literally larger than life. Snap shots up, down and in every direction to create stunning 360-degree immersive experiences that you can share on Google+ with friends and family-or you can add your Photo Sphere to Google Maps for the world to see."

"Android 4.2 brings other great goodies like Gesture Typing, which lets you glide your finger over the letters you want to type on the keyboard-it makes typing fast, fun and a whole lot simpler. Android 4.2 also adds support for wireless display so you can wirelessly watch movies, YouTube videos and play games right on your Miracast-compatible HDTV."

Price/models

8GB for $299; 16GB for $349; available unlocked and without a contract on Nov. 13 on the Google Play store in the U.S., U.K., Australia, France, Germany, Spain and Canada. The 16GB version will also be available through T-Mobile for $199, with a 2-year contract.

Reviews love the design of the handset and new version of Android OS.

"The LG-built Nexus 4 is an improvement over last year's Galaxy Nexus, and I came away from my encounter quite impressed with the phone's performance and slew of interesting features," said TechHive

ComputerWorld was similarly impressed. "In terms of basic hardware and form, Google has clearly taken the best parts of LG's Optimus G -- the foundation upon which the phone is based -- and polished them to near-perfection. This is truly a melding of LG's basic hardware and Google's sense of design," said the site.
