Bill Gates showed off a concept ultra portable Tablet PC with a 7-inch LCD display today during his keynote speech at Microsoft’s WinHEC conference. Good old Bill says that the device is planned to have integrated WiFi, Bluetooth, and do all that tablet PC’s can do despite its small size.

Microsoft is pushing for ultra light, ultra small devices with long battery life costing between $500-$800. Who knows if this will actually manifest itself into something tangible for the consumer, but time will tell.
