Soon you'll be able to add Samsung to the list, as the Korean electronics giant plans to release a keyboard-based micro PC of its own, called the SPH-P9000, in South Korea during the first half of next year.

Unlike the micro PCs from OQO (the model 01+) and Sony (the VAIO UX), both of which feature mini thumb-keyboards, Samsung's device is unique because it flips open to reveal what appears to be an almost full-size keyboard. When closed the SPH-P9000 is still supposed to be no bigger than a typical portable DVD player.

The SPH-P9000, which runs on Windows XP Professional and weighs a little over a pound, also features a 5-inch WVGA LCD and a 30 GB hard drive. Internet connectivity options include WiMAX and CDMA EV-DO. Reports say you'll be able to make phone calls with the device as well.

It is not known at this time what the SPH-P9000 will cost or if Samsung plans on shipping it in markets outside of Korea, such as the United States and Europe.
