I'm on an imac. Best move I ever made, and I've been doing this for a long long time. As soon as Apple came up with Mac OS/X, which is Unix essentially -- that was all I needed.
No more fatal exception errors. No more rebooting 5x/day. Everything works like it's supposed to, and on the occasion it doesn't, there's a fixable reason. It's great!
looks like I might have to try a full reinstall
