Orbutt - I'm not sure really what to think abut the new 620. It is almost identical to the 610, except for:
1.) added running metrics - have no idea what to make of those and no-one else does either. What does foot contact time with the ground mean? Or vertical oscillation?
2.) removed all the navigation features (no waypoints, or nag back to start) - stupid
3.) WIFI and bluetooth upload - now this is very nice
4.) Satellite positions stored so very fast acquisition times - nice
5.) VO2 max calculator - based on HR response, and actually quite accurate reportedly. However, if I am to believe mine, I'll be finishing my first beer when Jimbob crosses the finish line!
So, all in all, if your GPS watch is working well, I would not bother to change it.
