I've developed software under Kubuntu and Windows for years now. I found adapting to Kubuntu from a Windows world to be amazingly easy (ignoring the random Linux driver installation headaches). After a few days mucking around with some keyboard shortcuts and relearning Bash and I was all set.
These days, the center of gravity in the mobile development world is OSX due to iOS's market share, so it's time I bit the bullet and dive into the Apple world.
I'll admit, transitioning to OSX has been mind numbingly painful at times. (Apple, why do you persist on using such a wonky keyboard layout? Where's my ctrl+left??! No alt+tab?? wtf? ARGH.) I mentioned this to Matt Pritchard, a long time OSX/iOS developer, and he passed along a list of OSX utilities and tools that can help make the transition easier for long-time Windows developers.
Version support - Often it extends back further than listed if you download older versions.
