HTC developing touch tablet?

Cellphone maker HTC may be working on a previously unheard-of kind of tablet device, a Portugese site claims. Dubbed the "Magnum," the prototype tablet is distinguished by an oversized OLED touchscreen, larger than any currently on the market. It is also said to have an 80GB hard drive and 2GB of ROM, and operate using a 800MHz Marvell processor, 512MB of RAM, and a 128MB AMD graphics processor.

The accounts have engendered considerable media skepticism however, due to an incongruous feature set. Despite the size of the screen, it only supports 65,000 colors, and the system's overall battery life is said to be 30 hours -- as long as the much smaller iPod classic, and several times that of most notebooks.

The system also uses Windows Mobile as its operating system, rather than the more common choice for tablets of Windows XP. An extensive set of wireless technologies is supposed to be built-in too, including not just Wi-Fi and Bluetooth 2.0, but WiMAX and 7.2Mbps HSDPA. Finally, the Magnum is said to weigh only 1.6 pounds, lighter even than Apple's MacBook Air. No commercial products have as yet been attached. [via Boy Genius Report]
