Now with greater battery life and fuller features, netbooks have evolved away from the realm of supplemental secondary machines. Ten-inch mini-machines with 4 hours battery life and processor power decent only for web browsing are things of the past. The HP Mini 311, for example, packs enough performance punch to display high-definition video content with an ease akin to larger, more robust systems and models like the Samsung N140 or the Toshiba NB205 holds enough juice to last a cross-country flight or a full workday. These six machines are the cutting edge of netbooks.
