I jumped ship in snow leopard days when I saw what they were doing with their shared object formats (basically making my life difficult for no reason). I've used Mint since then; never looked back. Mint on an old X220 thinkpad is better than anything mac has done since then. Requires a bit of overhead on setup to get power management right, but I paid that price years ago and can endlessly clone HD images. Bonus is, most of my work product ends up on the EC2 anyway.
