I'm also a Garmin Edge 305 user.
I like it a lot.
Like the fact that I have 3 bikes and one computer (although I keep the wired one on my commuter as a check on the Garmin, as it doesn't work so well in a city with large buildings or in the parking garage where I park the bike).
Like the coolness factor of the datapoints (but be careful not to load too much onto the display screen...you can get overloaded with too much info...best to save a lot of that for looking at AFTER the ride).
I like heart rate and cadance and checking that out vs. other ride metrics like elevation, % grade, speed, etc.
Dislike the fact that I can't correct obvious errors in the file (like, my 325 mph max speed).
Dislike the fact that it doesn't give me turn by turn directions for a new route but maybe I was hoping for too much!
Not a big fan of the stock desktop application. Susan - how do you like MotionBased? Do you use the freebie or are you a subscriber? Is it worth the switch?
I also don't like the fact that I know I'll never use it to its full capacity.
I'd love to hear your impressions, SB.
