Roundup: 7 Ultraportable Laptops

PC World magazine's roundup of ultraportable laptops includes machines that weigh under 4 lbs. It includes four models from Lenovo and one each from Sony, Samsung and Apple.

"You have to take only a couple of business trips or vacations with a 6-pound laptop in tow before you start thinking about switching to a PC with a little less meat on its bones.

Although 14- and 15-inch all-purpose laptops are abundant and often inexpensive, just throw one into your backpack or briefcase and lug it around for a few days--your shoulders will soon beg for mercy. These days, fortunately, you can find plenty of laptops on the market that are slimmer, lighter, and more powerful than almost anything that you could have bought just a few years ago."
