Dell XPS 13

Pros: Light and thin.

Cons: *** No Hibernation.
*** Trackpad/touchpad very irritating to use, very jumpy or hardly moves.
*** Screen can only be opened very little past vertical.
*** Minimal ports. 1 USB 2, 1 USB 3.

Summary: I highly recommend not to buy this XPS 13. You will avoid a lot of headaches. It is apparent that Dell released this model before ironing out many critical issues. For the price we users deserve a much better finished product. Here is why:
Cannot hibernate, and Dell knows it and cannot fix this critical issue. Cypress Trackpad is irritating to use , even with driver update, Dell should install a much better trackpad/touchpad hardware for this expensive laptop. Screen cannot be opened too much past vertical making viewing standing up nearly impossible. Having SSD the Windows Defrag was not disabled as it should have been, it was scheduled, which is a big no no with SSD drives.
Seriously thinking of returning this troublesome and irritating ultrabook.
