I have the 2nd generation XPS13, with 1920x1080 screen, and absolutely love it. One caveat: the left side USB-3 port on most earlier versions of these machines can really only handle USB2 speeds, not USB3, due to poor design of an internal ribbon cable.

A buddy of mine got the next generation (same problem) with touch screen, and has been very pleased with it (running Ubuntu Linux).

The one you are looking at is one or two generations newer again, and they have probably fixed the USB port by now (looks like a full redesign).

Cheers
