I had the same model, but with the added touch display function. Unfortunately had the old Lenovobook after exactly 14 months (2 months after the warranty) a defect of themselves so far can not be repaired by Fachgeschäfft (laptop starts, fans, lighting etc, but remained the display goes dark) I was otherwise very happy with the U330p touch, quick easy work, good stable performance in everyday use (Netflix, Youtube, all good), so a new purchase, this time without giving the touch panel.
Have bought the Lenovo U330p in a large well-known electronics market. Arrived home I realized that the device is not completely flush, which tap an absolutely annoying rattles when using the touchpad and led. Also, I find the screen a total of a bit too dark, I liked much better in the Touch version. Not much more I can not say for U330p because I have returned the device immediately. The staff confirmed that the unplane resting vorkäme frequently.
