nah. I switch between windows, linux, and osx for work and personal use all the time. OSX is just fine. Windows is just fine. Linux is just fine. Everything is at about the same level of ability, the same level of suck, and the same level of "just works." Every modern OS is good looking, occasionally frustrating, and generally effective once you take a few days to figure them out.
That's how I feel about it. There is a convergence towards common usability as long as you choose your graphics card carefully for GNU/Linux (no nvidia).
