Accented by a shiny black lid and real leather wrist rest, the $2199 (as of April 11, 2007) Asus U1F puts the "ultra" in ultraportable. The lightest Windows Vista laptop we've seen, it weighs 2.4 pounds, no heavier than a teacup Chihuahua. The thin case offers a surprisingly full set of connections, including built-in Wi-Fi and Bluetooth wireless communications. You could use the bright screen to find your way out of a cave, and the battery lasts for more than 6 hours on one charge. These are good qualities for an all-day, on-the-go laptop to possess. But can you type on it? (pcworld.com)
