Asus is calling its new P565 smartphone the "fastest business PDA phone in the world." The Asus P565 does indeed have some impressive specs with an 800MHz Marvell processor. That should give the Windows Mobile OS-based smartphone ample power to multitask a number of Microsoft Mobile Office apps at the same time.
The 2.8-inch 480 x 640 touchscreen is a decent size for navigating the Glide (iPhone-like) touch interface, which runs Windows Mobile 6.1 OS. Given the amount of wasted space on the P565's front, however, I'd like to see a larger display.
