Intel's Handheld Personal Server. The personal server mounts on any PC that can recognize wireless devices: “Any computer becomes your computer,” said Want. MP3 enthusiasts can sidle up to any computer that recognizes wireless devices, and exchange files using the host computer's keyboard, mouse and screen. Other potential applications for the personal server include sensor data retrieval for science and biomedical purposes, and presentation and other mobile computing applications for business users. The personal server runs as a Web server on Intel's 400MHz XScale processor, and connects to PCs and wireless “information beacons” via Bluetooth and wi-fi. The device also takes advantage of the motes radio technology developed at UC Berkeley. The personal server also makes efficient use of power: it can stream video for 4 1/2 hours without running out of juice. [Smart Mobs]
