In terms of releases, Motorola won't say anything about the Xoom's UK release date, though it is pencilled in for the first quarter of 2011 in the US.

But HP has been a little more coy and we could even see the HP TouchPad arrive in the autumn.

This is the biggest difference between the five tablets. The iPad runs Apple's own iOS, the Moto Xoom and Samsung Galaxy Tab 10.1 both pack Android 3.0 Honeycomb, the BlackBerry PlayBook runs RIM's own Tablet OS and likewise the new HP TouchPad also has a bespoke OS. The Touchpad will run Palm's webOS, first developed by Palm - who HP then bought. The tablet will run webOS 3.0.
