Isn't that along the lines of System 76 [1]? I haven't tried any of their machines, and they aren't exactly trying to compete with Apple, but they are Linux first.
It appears that they are essentially a reseller of Clevo / Sager laptops, though. On the plus side you are guaranteed good support for the hardware using most distros, the build quality looks to be a bit below, say, a Dell XPS, though.
