Yeah, me too. I have a linux computer for most development, a Macbook when I want to mess around with iOS development, and a Thinkpad for .NET development. All of these are tax write-offs and since I use the linux computer (which twice as old as the other two, by the way) 90% of the time because it's simply easier to install development related stuff. Whenever I want to install a gem that uses native headers requiring a -dev package in OSX I just quit.
