Yeah, I never look at my HRM while I'm riding, but I do like having the numbers for after. I do use the HRM for running - but on the bike I just ride, I don't train. I like having the cadence monitor - I have a pretty good sense of my cadence, but I'll fine-tune it with the monitor. In a paceline, I use the timer and speedometer when I'm pulling to time my pulls and make sure I'm maintaining a constant speed.
What I really, really need the gizmo for on the bike is MAPPING. I have the world's worst sense of direction AND a phobia of being lost. (A true phobia I think - we were discussing that in another thread - I get really panicky.) Not a good combination. So having the maps is an ENORMOUS comfort.
