Had acquired in November for 799 Ultrabook (8GB / i7). From the performance I'm really excited, the boot process is very fast, the processing is super. What bothers me: Although the display is sufficiently bright for my needs (working at your desk, the outdoors may look different), but the display flickers with low brightness in dark graphics. Increasing the brightness fixes the problem for 90%, but a shame when such an expensive device. Another drawback: The hinge is not really stable. The appliance is heavy enough to provide a stable display can. The display wobbles quite strong when you use the touch screen. For this you can see every fingerprint on the glossy display. The hand support surfaces made of aluminum in front of the keyboard are quite sensitive to fingerprints. I will keep the device despite the small shortcomings.
