I switched to linux. I like it and haven't really had any issues to speak of. Not with sound, video, wifi or any of the other things people complain about. My fan went, but likely it was a pet fur issue, and easy to fix... I'm not an admin. I know how to use the command line, and how to use it as a work machine. Really my experience over the past 3 years, its been as trouble free as my Mac used to be. It really is the great development platform.

Glad you like your machine.
