Lenovo's IdeaPad U150, which I called "dazzling" in a previous post, is now shipping for $699.
At that price, the system offers an Intel Pentium dual-core processor (SU4100; 1.30GHz), 3GB of DDR3 (1066MHz) memory, 250GB of storage, Intel X4500 integrated graphics and an 11.6-inch display capable of 1366 by 768 pixel resolution.
(You can bump the internal hardware specs to an Intel Core 2 Duo SU7300 1.30GHz processor, 4GB RAM and a 320GB HDD for $849.)
The laptop weights about 3 lbs. and is 0.75 inches thick. It comes preloaded with Windows 7 Home Premium.
It's available on Lenovo's website.
