For anyone who just wants a basic and solid developer machine and wants a good, nice HD display, then you should consider at the Dell Chromebook 13. It is a fraction of the price for the XPS 13, fully compatible with Linux, has an upgradable SSD, and is a little bit more Stallman-friendly. The BIOS can be flashed with a number of open-source BIOSes [1] [2] - this makes it even possible to run Hackintosh on it. The battery lasts a good 10 hours when new, and 6-7 hrs as of one year I used it constantly.<p>Unfortunately, Dell don't sell the i-version anymore and their website currently only showing the Celeron. I have the i3 version and it has been a wonderful machine.<p>1: <a href="http://www.reddit.com/r/chrultrabook" rel="nofollow">http://www.reddit.com/r/chrultrabook</a>

The battery life sounds like the nicest improvement, honestly. I've got the 2015 9343 version with the QHD+ screen running Fedora, and I'm lucky to get six hours out of it.
