Barnes and Noble lived up to promises today and launched the Nook, its own e-book reader. The device is unique in having both a six-inch E-Ink display and a 3.5-inch color touchscreen LCD that serves to navigate and browse books. Also unlike most other readers in its class, it has both 802.11g Wi-Fi as well as AT&T-driven 3G to download books from Barnes & Noble's online bookstore.
