My own favorite is the Dell XPS 13, which comes with Ubuntu
preinstalled but you can replace the distro with your favorite as the
drivers are open and custom kernel is public at Launchpad.net. Details

It's the last laptop I bought :-)

I've installed Debian and it works great. You don't need the kernel at Launchpad but you should use a recent kernel (3.4 or newer) which supports Cypress pad.
