Gigabyte M528 MID - small and light, yet powerful, like dynamite

It has a 4.8-inch screen, which should give you a reference for dimensions, and it weighs a mere 340 grams. Technically it's being called an MID or Mobile Internet Device, but it looks pretty capable.

It has a 3MP camera on the back and a 300k pixel camera for video conferencing as well. It has a slide out QWERTY keyboard for input.

You also get GPS and some sort of wireless connectivity that isn't mentioned, although I am sure it's at least 802.11b maybe more. No word on price or availability, but it looks like it was made to compete with the Nokia N800 and N810.
