Absolutely love my Dell XPS15 (9550)
15" Screen with no bezel so its about the same size as a normal 14" laptop. Not too heavy unlike most with these specs. Current i7, 512GB SSD, 16GB Ram...
Was a bit flakey at the start with a screen which would randomly flicker black for a millisecond every minute or so, couldn't tell if I was going crazy or just blinking... but a firmware update fixed it up after a month or so
