Dell today launched its all-new line of Latitude laptops, comprised of the 12-inch E4200, 13.3-inch E4300, 14-inch E6400, 15.4-inch E6500, as well as the 14-inch E5400 and 15-inch E5500. All of the business systems feature a new instant-boot function that allows users to access email the Internet without waiting for Windows to load. Likewise, all have wide-area wireless and a fingerprint scanner for security, with 3G, GPS and WiMAX optional extras. One of the highlight features of the new Latitudes is their claimed 19-hour battery life, which is unprecedented in the laptop world.
