Sitting here in the UK. Dell seem to have run out of their xps one 27 touch. Either that or they are in the process of updating it and offloading their old non-touch versions and have removed it for that reason.
I almost clicked purchase but, luckily did a quick check of the spec (like all us techheads do about 15 times before we commit) and noticed that it specifically stated non-touch for the screen. Couldn't find the touch version anywhere on the uk site!
