What is the compatibility like on a 2015 Macbook Air?

So I've always wanted a Mac, just for the nice hardware. Now I am thinking about buying the current Macbook Air: http://www.apple.com/ca/macbook-air/specs.html

But my only concern is Linux compatibility, I would still want to run Linux on it. Does anyone else have this Macbook? Does it work well with Linux? Is there anything that doesn't work?

Any help would be appreciated! :D
