Just got the Garmin Edge 20. Simple, Speed, Time, distance, and elevation only. All I need! Keeps history of all rides too. I love it, no wires and nothing attached to my forks or spokes. But then again I'm amazed that I have this tiny GPS computer on the neck of my bike, hadn't realized GPS had made it into the cycling world

There's a saying "if it isn't on Strava, it didn't happen." The sports world is big time into GPS. I use it in a wristwatch instead because that also tells me how fast I'm skiing in the winter.

There's an app for that! (I prefer Trace, but Ski Tracks is good too).

you are only six or seven years late for the party. Not too bad. On the other side, I was 27 years late realizing the benefits of STI's.
