The Lenovo ThinkPad X61 is an ultraportable business laptop geared to individuals who demand the best. Like its larger brothers of the ThinkPad line, it shares all of the same rugged features, as well as the creature comforts of a full-size keyboard. Although it is much smaller than its counterparts, it is every bit as fast. Light business travelers can rest easy knowing they didn’t sacrifice anything but weight when they bring the X61 on the road.
