I happen to use it with great success (*). Freeware needed is "gpsbabel" and "geosetter". The first creates proper gpx (including height info), the second processes RAW files in a great way.

(*) It features bluetooth (so you can combine it with PDA navigation), and auto ON/OFF with a motion sensor switching it on again when you move. So, you put it into your photo bag in the morning and forget about it until you go sleeping...
