I'm a VB guy also who would be interested in how difficult it would be to make that jump. I'm pretty sure you'll need to do it on the Mac with one of the langaugees they make available.

Did you install the development stuff with OSX? It's all in there I think.

After that? Google... or talk to Erica over at TUAW.
