Although I used Linux environments at university, I've been working in Windows environments ever since I left. I've tried working on Mac, but I find it so hard to create an environment to work in that I'm put off before I finish. I continually find myself returning to Windows, because it allows me to do the 'risky' stuff that I have the knowledge to do without patronising me (quite as much as Mac). Still, there are things to learn when setting up an environment for web development.
