I'm just hoping that if we keep bombarding them with ideas and feature requests for current models, that they will gradually make some improvements. The 350LM is their newest moto GPS, so I am hoping for some ongoing development. If it would allow more points in a route, show tracks, and allow me to kill some or all of the data fields displayed on the map, it would be damn near perfect. I know their track record is not great, but I will still try.
