The Lenovo IdeaPad U400 is one of those interesting machines that crosses the line between notebook and Utrabook. It's just 0.89" thick and 4.36lbs. yet it has full Intel mobile CPUs (not ULVs) and an optical drive. It's stylish, it's clad in metal and the price is downright excellent on this Sandy Bridge model.
LogicBuy has a deal code for 33% ($300) off on Lenovo's website, and that means you can get the machine for $599 with a Core i5 CPU, 6 gigs of RAM and a 500 gig hard drive.
