One day, you'll have a little tablet or phone, and carry it everywhere. It'll be your only computer. When you need to use a "real" PC, you'll dock it. Motorola's Atrix is a little glimpse at that day.
At 9.2mm thick, the Optimus Black from LG is the new world's thinnest phone, and is pretty light too, at 109g. It's also got a 4-inch NOVA screen for viewing in direct sunlight, too, and a 2MP forward-facing camera.
