The ThinkPad T430 is the perfect notebook for students who need lots of endurance. How much? Try over 13 hours of juice when you spring for the $50 9-cell battery. Plus, this ThinkPad can take a beating from your klutzy roommate, thanks to its rubberized ABS plastic lid, carbon-reinforced bottom and internal roll cage. Add in a redesigned keyboard that’s sleeker but just as comfy and you have a winner.
