There's a learning curve, but there is when switching from one technology to the other. I know I finally convinced my wife to get a MacBook Pro this summer and for the first month she hated, now she bitches when she has to use a Windows PC at work. I know a couple others that have tried it and never did get the hang of OS X so went back to Windows. It's all about your personal preference.
I have a MacBook Pro that I use at the office on a huge monitor and an older MacBook I use at home for the limited amount of work I allow myself to do in the evenings/weekends. The company gave us used Dell's, mine sits next to my desk hooked up to a small monitor that plays Netflix all day, that's it.
