Baby steps... maybe start with dual booting, or a VM, over time you get more and more comfortable as you find the bits you need on Linux or whatever. You will probably never find a replacement for everything, but eventually you get to a threshold where the "Apple Hates Me" vibes > "Not quite everything I want", then you have somewhere to go when you flip the table... You will probably still hate it initially, but the nice thing is that you can work on it, making it into what you want, and unlike with Apple or MS you can make progress... it will stay how you put it, because the authors of the software are not working against you. i.e it gets more comfortable over time, and less of a battle over time. Admittedly how easy this is, is highly subjective, e.g if you are a media person then it's going to be painful whatever platform you head to (although I hear audio and video editing alternatives are getting better).
