I also have an XPS 15 from work, and I run Ubuntu on it. It's a pretty solid laptop. At first there was a problem with suspend only working sometimes, but after a firmware update it doesn't seem to happen anymore. At first I didn't like the keyboard and used an external one, but after typing on it daily I really enjoy it. It has a good travel distance and feel, and it's plenty large. I'm glad it doesn't have the 0-9 numpad on the side either, so my hands are centered. The palm rest areas feel comfortable. Battery life is pretty good. The screen is fantastic and bright. I generally don't use the trackpad, but it seems to work just fine when I have had to use it. I don't ever use the touchscreen. If you do have a significant workload, the left side of the keyboard heats up rather unpleasantly. (Around the S key.) Sometimes after suspend or otherwise reconnecting on wifi, network-manager gives up, and I have to reboot. Overall I would recommend it!
