I haven't tracked mileage for years. I have a pretty good ball park idea of how far I ride, and increasing or decreasing my mileage by a couple thousand miles per year won't have any impact on how fast I am or how much I enjoy riding. OK, dropping by a couple thousand would decrease enjoyment, but I don't need a computer to tell me that.

I use the trip computer to verify that I've calibrated the gizmo correctly and also to help me figure out where I am on longer rides. But overall odometer isn't too interesting.
