A company called Seamless Internet was demonstrating their S-XGEN mobile computer/cell phone. This hybrid device features a GSM cellular radio combined with a personal computer running Pocket PC and featuring aTFT touch screen, fold-out QWERTY keyboard, 20 GB hard drive, Wi-Fi and Bluetooth connectivity all powered by an Intel processor.
The device was large and heavy - at 14 ounces - for a cell phone but quite small for a mobile computer. There's a possibility of a version running Windows XP down the line; now that would be a futuristic device.
