I think there's a market for a linux distro that targets a limited set of premium hardware. I'd gladly pay money for an OS that worked out of the box on any MacBook or Surface Pro made in the past two years.
Edit: Many people are replying with brands that work for them. I'm glad they've been lucky enough to avoid problems, but I am making a different point. On Macs, OS X is practically guaranteed to work out of the box. Wifi, bluetooth, trackpad, screen brightness, power management, hardware graphics acceleration, resume from suspend/hibernate, etc Just Works™. On Apple's hardware, users never have to worry about kernel flags or special drivers. The same is not true for any combination of laptop brand and linux distro. I truly wish it were otherwise.
