The 11.6-inch ThinkPad is the first laptop to feature AMD Fusion E-series Accelerated Processing Units. It offers a 30 percent improvement on batter life than the past model, and up to 65 percent better graphics performance thanks in part to its AMD Radeon HD 6310 graphics. With over 6 hours of battery life, this netbook is Energy Star 5.0 compliant and weighs only 3 pounds.

PCMag reviewed the Lenovo ThinkPad X120e and rated it a 4 out of 5, and said it's arguably the best netbook for business. It has a fast hard drive, and a best-in-class keyboard. The ThinkPad X120e also offers a phenomenal navigating experience with both pointing devices and pairs of mouse buttons.

Though the ThinkPad X120e is normally a lot more expensive than the typical netbook, this discount will bring the price down to the average netbook price, making the powerful X120e a reasonable option for your netbook purchase. But hurry, this deal ends August 10 or sooner.
