I purchased a copy of MacGPS Pro to use with my Garmin eTrex Legend Cx, mainly because it seems to be the only Mac product that can connect to USB-based Garmin GPS receivers. The purchase, download and install went well, and it can indeed talk to my eTrex. However, I've now returned it after a day.

The product has been around since before OS X, and it shows. Confusing arrays of options, long overly-technical popup menus, different fonts in different places (including some very ugly ones), eccentric work flow. It's possible that an expert in GIS and GPS technology would find it wonderfully flexible and powerful, but I for one found it painful and confusing.

MacGPS Pro looks like it has lots of features, and I don't doubt that the customer support is great (although all of the website's links to the company's return policy were broken). However, the product's user interface needs an extreme make-over. For now, I'm going to look into using Boot Camp to run a Windows-based application (which is saying a lot for a Mac-a-holic such as myself).
