As good as the best new smartphones coming out of Mobile World Congress are, it’s not all about the handsets in Barcelona. Almost every manufacturer has rocked up to the annual expo with an Android tablet nestled under its arm, and there have been some properly tasty devices unveiled - most of which are running the delectable Android 3.0 Honeycomb OS...

See our pick of the very best new tablets on show at Mobile World Congress 2011.

Acer Iconia Tab A500

The 10.1-inch tablet runs Android 3.0 Honeycomb combined with Acer UI to reach a "whole new level of interactivity", according to Acer. An aluminium casing adds a certain sleekness, fired along by a dual-core NVIDIA Tegra 2 chip, while a built-in HDMI port and 1080p output give it some beef on the visuals front. Throw in multi-touch screen and gyro meter control, Wi-Fi, 3G or Bluetooth 2.1, HD front-facing camera and 5MP rear-facing camera, and you've got a top tablet offering.

HTC Flyer Tablet

Constructed from a single piece of aluminium with white accents, its stunning build quality follows the same high quality as the handsets. A 7-inch 1024×600 pixel screen keeps the weight down to 415g, while an HTC spokesperson said it enables 'truly mobile use,' because it can be held with one hand. The Flyer runs a single 1.5 Ghz - rather than dual-core - processor with 1GB Ram. It also runs a new version of HTC Sense that has been optimized especially for tablets, the interface now includes what's described as a 3D experience with widgets moving in space.

LG Optimus Pad

The Optimus Tab measures in at 8.9 inches, which LG reckons is big enough to browse and watch movies on, while still being comfortable enough to use one-handed. Whereas the Optimus 3D phone uses similar glasses-free 3D tech to the Nintendo 3DS, its tablet brother will require special glasses. However, the Optimus Pad does boast the phone's 3D video recording, as well as full HD playback for videos. Under the hood there's Android 3.0 Gingerbread and a dual-core 1GHz Nvidia Tegra 2 processor.
