Instead of XPSs, we bought Precisions 15 5000 at work [1]. They are basically XPS 15, (virtually indistinguishable apart for the engraving on the bottom), but you can spec them to bits (you can even get a Xeon processor if you want,have them with no OS / Ubuntu). All of us are reasonably happy with them.

Another Precision user chiming in. I got one at work and after I updated the Intel video driver, I've had no complaints.

These look very good, thanks for the recommendation.
