|Microsoft's Courier Tablet|
The Courier has two screens that fold together like a book and has an external 3-megapixel camera. The device uses the increasingly popular poke-and-swipe method of touch navigation that works with fingertips or a stylus.While dazzling with possibilities of a sleek, portable touchscreen device, the tablet trend turns a troubling corner by shunning keyboards and threatening to take us back to a time when we wrote by hand. Judging by the prototypes, thousands of people will be jazzed by this cool innovation, but millions of laptop typists are going to be left behind. -- Written by Scott Moritz in New York.
