Motorola Atrix 4G mightiest smartphone yet?

The was the most advanced tablet that we got to try out at Mobile World Congress. Other tablets, including the , certainly look promising, but the Xoom is the launch device for the - the version of Android developed specifically for tablets - and the devices on show at MWC were fully working ones used for live demonstrations.

Motorola marketing director Tom Satchwell gave us occasionally pulling out his very own Xoom to demonstrate a feature that he actively uses on it.

The Xoom certainly makes a compelling case for the Android tablet platform. The 10.1in screen device is being pitched by Motorola as a showcase for the Honeycomb "multitasking operating system" and it cruises along on a 2GHz Tegra 2 chipset and 1GB of RAM.

The 16GB tablet has a 16:10 physical aspect ratio, but the viewable area is 16:9 - the same as Blu-ray movies. An extra portion of the screen has been reserved for what Motorola terms a "persistent navigation bar". This saves the user constantly jabbing at a hardware button to go back, back and back through menu screens. Should you wish to use the Xoom for viewing a TV program, the navigation bar dims so as not to be distracting.

Other aspects we really took to include the support for 3D maps that Google has added to the and the Motorola Media Link function that "sucks DRM-free content from iTunes, for example, and on to the device". Motorola is not the only manufacturer to acknowledge the power of and that consumers need reassurance that they won't lose what they've invested in their iTunes music library by choosing an Android or non-iOS tablet.

However impressed we were by the Xoom, however, it was the that showed where mobile technology might really be heading next.
