I haven't used one but it looks pretty cool. I have used a Garmin eTrex Legend C for a while. I think any GPS that gives you a map instead of just coordinate numbers is the most useful feature. I don't know if your eTrex did that, but you might enjoy using it more if it did. IMO I still use larger paper maps too. I just travel a bit more casual knowing I can turn on a GPS and pin point my location when needed. I do lean on it when bushwacking in thick brush and heavy terrain. But mostly I journal waypoints, campsites, trails, and other point of interest.

Now they're combining the SPOT satelite features in one unit. It also expands the communication features of SPOT beyond your chosen pre-trip text message. I don't know if the latest version of SPOT does that. Be nice to hear from SPOT owner/users about this too.
