Having been in the same boat, I found the switching learning curve to be vastly overestimated.
I guess I'm just skeptical, then. I get irritated when I use them because there's a ton of stuff on the desktop and I still can't find where anything is. Certainly nothing about the experience that would make me want to switch to a Mac, although I assume that if I'd been using them instead of PCs all these years I'd be accustomed to it and not want to switch from the Mac.
