I switched to Macs years ago. I now have a Mac at work, one at home and a Mac laptop. Yes, there is a wider range of software (e.g. stats programs) available for PC type platforms, but I wouldn't go back if you paid me to. Learning how to use a Mac takes a little time, but much of it is much more intuitive than Windows. Having said that, Mac is in danger of falling into the same trap as Windows, with newer operating systems being unnecessarily more complex than older ones without any discernible improvement in performance.
