I have a Garmin 705 & about 4-5 mounts that I change from bike to bike. It's nice since it doesn't required anything too intrusive or obtrusive to mount. I like to track mileage, stats, elevation changes and routes, so it's a great geek-toy. I enjoy vintage bikes for the quality of workmanship, feel of the ride, history, etc., not to show off how authentic I can be. I'm not a big fan of museum pieces, so I'll put the Garmin on anything for a ride and take it off when I'm done. No big deal. I rode 20+ years without a computer of any sort. The only time I ever knew how fast I was going was if someone in a car yelled "hey, buddy, do you know you were going XXX?"...which, actually was kinda helpful or at least interesting...
