I don't have a cycleputer and don't want one. For an IT support tech, I'm really low tech away from work. Part of bike commuting and becoming car free was to simplify my life as much as possible. If I want to see how far I rode or will ride I just map it out on http://www.gmap-pedometer.com/. I commute about 15 or 16 miles RT 5 days a week and put in several (usually easy) miles on my days off doing store runs, errands and joy rides.
