It's a Keyboard! No! It's a PC! By STEPHEN WILLIAMS The idea of containing an entire computer -- including display screen -- on what is essentially just a keyboard, has been in the fermenting stage for some time at Asus. Enter, this month, the all-in-one Asus Eee PC Keyboard, which is finally shipping, at a price of $600. It's a handsome piece, not particularly radical; it looks like a silver-finished keyboard. The centerpiece, which is to the right of the full-size keys, is a five-inch, rectangular, 800-by-480 LED-lighted touch screen, which looks a lot like an iPhone. It is very crowded inside that slim wedge of a touch screen; Asus found spots for a 16-gigabyte solid-state drive, a gigabyte of RAM, Wi-Fi and Bluetooth chips, plus video outputs (including HDMI) and U.S.B. ports. Processing power comes from an Intel Atom chip. The computer runs Microsoft Windows XP version, not Vista. The device is not meant to replace a laptop for mobile workaholics. And it won't. The display is useful mainly as a window for Internet browsing, e-mailing, Facebooking and receiving RSS feeds. To Asus, the device is a desktop replacement or supplement. But in practice, it behaves like ...well, a keyboard, with nicely clicking keys. Although the screen to the right side is bright and crisp, I would not get rid of that LCD monitor just yet. The device was first shown in January 2009, at the Consumer Electronics Show, and its introduction was an on-again, off-again affair, as the company waffled on specs and release dates for months before the "formal" release was announced earlier this month. It is now available for purchase at retailers including Amazon.
