BARCELONA, MOBILE WORLD CONGRESS — Sony’s initial unveiling of the Xperia Tablet Z came just after CES back in January, so Mobile World Congress here in Barcelona this week is the first chance we’ve had to get our hands on it. On paper, the device is very impressive, featuring a speedy quad-core processor, a high-resolution display, and a sleek form factor that measures just 6.9mm thick and boasts water resistance.

But specifications aren’t everything; we were itching to find out what the Xperia Tablet Z is like, so we went hands on with it this morning to find out.

BARCELONA, MOBILE WORLD CONGRESS — Here at Mobile World Congress in Barcelona, a company called Paragon is showing off an awesome new tablet dock called the cTablet Docking Station. It lets you mount your device within your car’s dashboard, providing you with a cutting-edge in-car entertainment system that’s already full of all your media, your navigation apps, and lots more.

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.

BARCELONA, MOBILE WORLD CONGRESS — Thanks to the original PadFone’s rather disappointing start, we thought the probability of seeing a successor at Mobile World Congress was slim at best. But we couldn’t be more wrong. Asus has just unveiled the PadFone Infinity, a 5-inch smartphone that transforms into a 10.1-inch tablet with the help of a clever docking station.

The device has some impressive specifications, including a 1080p display, a quad-core Snapdragon 600 processor, and a 13-megapixel camera. But do you really want a smartphone that transforms into a tablet? We went hands-on with the device to find out.
