The hardware is a real selling point, I researched a little before buying my current MBP, but none of the non-mac laptops convinced me. The Mac ARM processors are just that good, it seemed I could only get similar performance with twice the wattage and case size.

Then there's the issue (maybe personal) that I don't trust Linux not to give me trouble with drivers. Network drivers in particular are a pain in the ass to deal with because, well, you're out of a network connection (persistent broadcom card issues in the past).
