I've got the XPS 13 standard edition (max-specced refurb was half-price of the dev edition!) and it's been nearly smooth sailing.
One difference between the dev and std editions is the wifi chipset - 6235 in std, 6230 in dev (and some reports of the AR9462 in others). The wifi was practically unusable for me until I manually disabled power-saving on the wifi interface.
Also had a couple of instances where the machine has dropped into a coma (even on full battery). Usually after rebooting or suspending. Quite scary when it happens, since the long-hold power button trick doesn't always revive it. It usually comes back to life later but I wish I knew what was causing this.
Also have to run the battery all the way down to 0% (the point at which the HW forces a shutdown) and charge back up to 100% every couple of months else the calibration goes wonky.

Lovely machine though.
