I know your pain. I recently bought my 1st GPS & have run into the same issue. After all the research, I decided to get myself a Garmin due to their announcement that they will begin directly supporting OS X late this year. In the mean time, I've simply put an old copy of Win2K on an old junk machine so that I can upload waypoints, maps, etc. Virtual PC is worthless if you have USB based GPSr like I do. The driver just plain doesn't work across Virtual PC, so don't waste your time. I'm personally just toughing it out until [hopefully] later this year when Garmin begins supporting Mac.
