Montevallo II. This concept notebook, designed by Intel, features a screen that slides along a track. When pushed all the way back, Montevallo looks like a regular notebook. When slid forward, the keyboard is hidden from view so it won't distract you when you're watching movies. The screen can also be folded back on its hinge to turn the notebook into a tablet.
The ultramobile PC
The ultramobile PC, or UMPC. These devices, which have screens measuring 5 inches to 7 inches across, come with the same software and hardware as standard notebooks. The idea is that these devices will serve as portable entertainment centers, BlackBerrys and also sometimes cell phones. The first ones come out in a few weeks, according to Mooly Eden, vice president of Intel's mobility group. The UMPCs are somewhat experimental, Intel admits. While Sony and others have tried these before, they have been priced at about $1,500. The UMPCs will sell for under $1,000.
