BARCELONA, MOBILE WORLD CONGRESS — Have you ever wanted to make a phone call on your tablet? No, me neither, but clearly someone at Asus has. Here at Mobile World Congress in Barcelona, the Taiwanese company is showing off its new FonePad, a 7-inch tablet that makes phone calls just like a smartphone.

The device costs just $249, and it has mid-range specifications that will allow it to compete with devices like the Google Nexus 7 and the Amazon Kindle Fire HD. But is its special feature worth the extra cash?

BARCELONA, MOBILE WORLD CONGRESS — HP famously bowed out of the tablet game when it gave up on the TouchPad and its webOS operating system, but here at Mobile World Congress in Barcelona, the company has jumped right back into it. Its new tablet, the Slate 7, is an entry-level device that’s powered by Android, and it costs just $169. We went hands-on to find out whether it’s worth it.

Archos has today unveiled a trio of new ‘Platinum’ tablets, with displays ranging in size from 8 inches to 11.6 inches. These are the most advanced tablets the French company has released to date, and it has clearly taken a leaf out of Apple’s book when it comes to design. Not only do they look a lot like the iPad from the front, they also have similar displays.

The 8-inch model offers a 1024×768 resolution, just like the iPad mini; while the 9.7-inch model has a very impressive 2048×1536 resolution, just like the third- and fourth-generation iPads with Retina display.

A couple of days ago, Google started rolling out the Android 4.2.2 Jelly Bean update for the Galaxy Nexus, Nexus 7 and Nexus 10, with the Nexus 4 joining the list today. The update is being rolled out over-the-air, so it can take up to a couple of weeks or more for it to be available on your Nexus device.

If you have root access, you can easily install the update manually. If not, you can try to pull the update manually from Google’s server. Depending on your region and your luck, you might just be able to manually initiate the OTA update on your Nexus device. Here are the steps you’ll need to give it a go.

Google began rolling out its Android 4.2.2 Jelly Bean update earlier this week, and it looked as though the software would bring nothing more than a few important bug fixes. But after used their devices after upgrading, Nexus owners have begun to notice some changes throughout the OS.

In addition to better download notifications, Android 4.2.2 brings some changes to the Quick Settings pane, and a number of new notification sounds.
