Lenovo ThinkPad T40
ThinkPads are catnip to business travelers, thanks to their sturdy construction, solid performance, roomy keyboards, and–in the case of the Lenovo ThinkPad T40–excellent battery life. Our test unit came with a nine-cell laptop battery , which added considerable bulk but delivered 7 hours, 59 minutes of battery life. Like some ThinkPads, the T40 also gives you a choice of pointing devices: a nub as well as a touchpad. It’s great to have both, though the dual sets of pointer buttons can cause accidental presses. The T40 is available online for $1289 and up
