The Dell XPS 13 and 15 computers are excellent. The XPS13 weighs almost nothing and bodes an impressive edge-to-edge display. So you achieve a 13" screen in a traditional 12" footprint. Same goes for the XPS 15 ... 15" display in a 14" footprint.
I've used a lot of Thinkpad, Dell and Vaio computers over the years and the XPS15 is arguably my all-around favorite machine. Plus it has one of the new USB-C ports. Battery life runs around 7 hours of realistic use.
