Last week we ran our review of the Lenovo Yoga 3 Pro, a 13-inch laptop that weighs a scant 2.6 pounds and measures just half an inch thick. It was impressive, to be sure, but it won't be the last: Thanks to Intel's new Core M chips, we're about to see a ton of impossibly thin notebooks. The latest comes from HP, whose just-announced EliteBook Folio 1020 weighs as little as 2.2 pounds and measures 15.7mm thick. We say "as little as" because when the thing goes on sale early next year, it'll be available in two flavors: a regular version that weighs 1.2 kg (2.6 pounds) and a special edition that comes in at 1kg (that's the 2.2-pound one). Both are light, as I found in my brief time with them, but the 1kg model is noticeably lighter, so you might want to wait for that to arrive, if either of these strikes your fancy.
