The design goal: a full-featured mobile PC small enough to fit in a pocket. Weighing just over a pound, this PC has a 4.5-inch touchscreen that slides up to reveal a keyboard. A U.S. version is expected soon, starting at $2,000.

With a clamshell lid that can flip up and rotate 90 degrees, this 3G phone has a high-resolution, 2.6-inch widescreen display perfect for watching digital TV broadcasts aimed at Japanese cellphone users.
