I think that’s a lot about personal preference. Do you enjoy your machine? That you can’t repair it? That you can’t easily take your OS with you one to a machine from another manufacture? Maybe you don’t care. I do. I think Linux gives you a lot of freedom, but if you don’t need or want it, I don’t think there is a reason to change. I mean, apart from the whole Apple-being-a-big-coorporation-that-actively-hinders-reparability issue that one might care about from a societal and environmental perspective.

Maybe you could get all the same stuff you need for development in Linux, and a lot more freedom to boot.

I apologize that this comes off a bit hostile. I am a bit hostile. I am also sorry for it!

Perhaps you shouldn’t. Any honest Linux user will tell you up front if that if you have a comfortable system already it may not be worth the disruption in your workflow while dealing with the learning curve. That being said, being free from the whims of Apple is a nice feeling.

EDIT: I’m not sure what the state of virtualization is on the Mac side right now but it wouldn’t be the worst idea to fire one up and try out a distro or two. Kick the tires before you think about committing.
