Meet CherryPal:
The CherryPal™ C100 desktop is about the size of a paperback book, but has the performance you would expect from a full-size desktop computer. Freescale’s fast triple-core mobileGT processor delivers exceptional multimedia performance and feature-rich user interfaces, while only consuming as much power as a clock radio. CherryPal uses 80 percent fewer components than a traditional PC, and because it has no moving parts, it operates without making a sound and will last 10 years or more.
You pay $249 for a small black box with external VGA, 2 USB ports, 256M ram, 4G NAND, 400 Mhz processor and internal wifi card. This thing will consume about 2 watts of energy (they say). This acts as a thin client, as you run all of your application on your virtual desktop, in the cloud. And you get 50 Gb of free storage. Hope it’s not 100% based on S3 :-). And they let you run Opensource applications like OpenOffice, IM, mail, etc. But they say they have iTunes also.
