One of the first companies that will announce such an UPC is OQO. The device will feature a 1GHz processor from Transmeta, a 20GB hard disk, 256MB RAM, a 800*480 display, thumb keyboard and a thumbwheel. It will run Windows XP and its weight would be 14 ounces (about 400g), and measures 4.1 x 3.4 x 0.9 inches (10.4 x 8.6 x 2.29cm)
It also will be highly connective, with built-in 802.11b and Bluetooth wireless capabilities, FireWire and USB 1.1 ports, the company claimed. It provided no price for the device.
"With the growing list of companies supporting the UPC category, we see the potential for a revolution to take place in the computer industry," Dr. Matthew R. Perry, Transmeta's president and CEO said in a statement.
However, the list of UPC supporters does not yet include the names of leading PC vendors. Besides OQO, the supporters include mobile keyboard vendor Think Outside, multimedia storage vendor Silicon Motion, and data synchronization Pumatech. Notably missing are the Dells, Gateways and Hewlett-Packards of the world.
