I was so hoping that the iPad would have a gps chip in it. Then I could buy some maps and have a large screen GPS that also played tunes, surfed the web, and did another 100,000 of so things (different apps). But I don't think it does. So Garmin is really the only GPS company in town and it shows in their products, service, and prices. On the Mac side I did find a program called Routebuddy that claims to talk with the ZUMO 550 and a bunch of others. Might want to check into that. Let me know what you find.
