First off, the lucky XPS 10 owners that downloaded the new updates that systems work the same, well I wish I were you guys. I however didn't get out so lucky. Here is my story. I got a replacement XPS 10 Tablet in the mail today that seemed to work fine.

Oddly enough it seems that the track pad/mouse pointer stops working when the screen is black. e.g. during the time the screen is black the pointer on the screen doesn't move. I thought it might be related to the back light on the keyboard or the touch buttons.

If you are thinking of buying or currently own a Dell XPS 17 (L702x) good luck. I purchased my laptop in march 2012 and I personalized the purchase for high end performance. I have had nothing but trouble, pain and suffering, from this unit.
