Dell, HP and Toshiba have all announced new business-class notebooks for the fall season, and the focus is on battery life, weight, durability and security.

The company announced two breakthrough features for the fall - Latitude mainstream E6400 and E6500 models can support an extended 19-hour battery life, while the E4200 and E4300 ultra-portables are equipped for the upcoming instant-access-to-email-and-Web feature (no booting into main OS necessary) called Latitude On.
