Have you ever used said MacBook intensively with OSX? I guarantee you the difference in trackpad performance will be mind boggling and frustrating. Literally the only thing keeping me away from using Linux.
I'm extra careful with compatibility claims after the number of times someone says how Linux works great on whatever Mac, or Mac OS runs great on a Hackintosh, only for me to discover how many "inconsequential" things are broken. Like it'll not sleep, not have wifi or bluetooth, run the fans at 100%, and be missing various forms of hardware accel.
