I switched from Linux to a Mac a couple of years ago. What I found was that I was spending a lot of time on system administration and wasn't benefiting myself or anyone else. There were too many cases where things wouldn't work unless I dug down and found an obscure file to update to make things work. And no, I'm not talking common ones like /etc/resolv.conf. The free software answer is to modify the code to improve the programs, but I don't have the time to do that. I tried a Mac that I inherited, then bought a Mac Mini, then finally a MacBook Pro. I still have my Linux computer, but it is in my closet turned off for over a year. I've installed Linux on a couple of desktops at work but don't really use them much, and when I have problems I'm reminded why I switched to a Mac.

I will say that Ubuntu is a lot more convenient than the plain Debian I used to run and I might like Linux on the desktop if I tried it again. I've found, though, that I have a lot more apps I rely on on the Mac than I did with Linux so it would be a lot harder to convert back to Linux than it was to come to the Mac.
