Not much. Both System76 and Dell's Sputnik spend quite a bit of time getting good support for their laptops under Linux.

I personally think XPS has a much better design for a laptop.

It is actually available to buy right now. The Xps 13 developer edition is not available and the Windows edition has different hardware which is not Linux compatible (WiFi).

Yes, it is available: http://www.dell.com/us/business/p/xps-13-9360-laptop/pd?3x_n...

Excellent I've been trying to buy one for a while. Now to find it in the UK site...

It used to be that you had to use Windows to update the bios and that grub didn't work so dual boot was not possible. Also broadcomm.

Glad if that has changed!

Can't speak for the xps13 but I got a xps15 (Windows, no Linux option) about 6 months ago and everything works as expected.

Depends on what you care about. If you want are willing to sacrifice a bit of performance for longer battery life and lower weight, then the XPS 13 wins handily. If on the other hand you're willing to sacrifice (quite a lot of) battery life and accept (a lot) heavier weight in exchange for performance, then System 76 will sell you some of the fastest laptops money can buy.

Then you're not really into this mobility thing?

Mobility is relative. They may want desktop level performance that can be moved more easily than lugging around a tower/monitor/keyboard/mouse. Not everyone needs (or cares about) the ability to work away from a power source for more than a few hours.

Mobility is relative. Back when I split my time between two offices and occasionally worked from home I would have loved to have a decently powerful workstation that I could easily transport in a backpack.
