HTC, the manufacturer of a lot of Smartphones and Pocket PC phones, are now moving into the Ultra Mobile PC market too.

HTC Shift Ultra Mobile PC

Yes, it runs Windows Vista, including Aero and it features a 7 inch touch screen. The specs are as follows:

VIA CPU (the one we tried had a 1.2GHz chip).
Windows Vista Business Edition.
7-inch sliding, tiling wide-touchscreen.
30GB drive.
Tri-band UMTS / HSDPA, quad-band GSM / GPRS / EDGE .
WiFi, Bluetooth 2.0.
Biometric reader, front-facing camera.

Microsoft pushed the development of the Ultra Mobile PC devices over the last couple of years, as a sort of mini-Tablet PC. With a number of manufacturers releasing models. Its definitely good to see more manufacturers join in with such a wide array of devices to try and push the price point down, hopefully to the point at which I can afford one.
