I don't see much point to a GPS computer that doesn't offer any way to transfer data to an activity app or website, or to ones own database. I suppose the GPS could make it easier to get a speed estimate for folks who don't want to bother with attaching magnet or earth induction sensors.
While I have some reservations about the XOSS G+, it does at least do pretty well at syncing with Strava and Training Peaks. I'd prefer it would enable easy data transfer via the USB port to my own records, or other app/software.
