There are some good mapping app's for Macs currently, but unfortunately nowhere near the variety that is available for Windows. That is pretty much the only reason I have a Windows machine for my portable computer. I have no less than seven mapping programs currently installed. I think the situation with Macs will change though, and we'll see more and more options becoming available. My Windows machine better survive until then, because I don't know if I can do this again. . .
