I have both air and xps 13 and to me they are not even comparable. Yes, thin bezel looks cool at the first glance but that's about it. Instead of metal under your hand you have this weird something, keyboard works much worse, they did not even make reasonable handle to open the laptop like there is in macbook air. Also the power supply is chunky and you cannot fold it nicely.

Don't get me wrong, it's a really good laptop and I've chosen it over so many others on the market. I would probably still choose it for my linux laptop (lenovo x1 is neat but I'm done with lenovo with all the stuff they've done lately). It just looks poorly to me in a direct comparison.
