Runs absolutely smoothly, complete Windows (no RT). very good is the 1: 1 USB port, no adapter Hurra. Battery life as 5-6 hours, under normal use and the screen brightness medium heat. Volume is very good, you really have down rules, as otherwise the internal speakers are overdriven. Have run on this device Traktor DJ software with external controller (USB). No outs, and other delays. Mileage TOP. In my notebook AMD 64 Core2 2Ghz gabs problems here and there with dropouts. Now nothing.
