Summary: The new IdeaPad Z400 Touch gets the expected upgrade - the touchscreen. The machine has been given an uncanny resemblance to the IdeaPad U-series ultrabooks. The performance is good, and the fairly powerful graphics can handle quite a bit of the fun stuff. However, all this excitement is tempered by the poor battery life. For around this price point, the HP Pavilion m4-1003tx seems to be the better deal.
