What do you guys think of these laptops?

Solution
I'd love to have the XPS 15 (the 13 is too small, IMO). But I'm not sure about the 4K screen resolution. I don't understand the point of that high a rez on such a small screen. And many programs don't scale well on a 4K screen, from what I've read. Doesn't mean I wouldn't consider one, but I'd want hands-on experience with one first.
