In addition to the new Google Android 3.0 Honeycomb OS, Andy Rubin previewed a rather interesting piece of hardware, Motorola's prototype Tegra 2 tablet.

It is still not clear whether this is the rumoured Motorola Stingray tablet that should appear on Verizon, or something that will come a bit later. One thing is clear, that the prototype tablet has Nvidia's dual core 3D processor, or simply Tegra 2.

The prototype tablet works like a charm and looks quite good, although during the presentation Rubin wasn't keen to reveal all the detail or even show some of that processing power behind that little Tegra 2 chip, but it is nice to know that Motorola has it. Of course, price or even a hint regarding the availability date haven't been announced.
