after a little over ten years of commuting, i don't know why i even use one. my bikes all have them on, but on my commute, i just don't know what the point is. i know it's 19.9 miles. i know it's about 85 minutes there and about 70minutes back. when it matters, i also know the temperature before i leave in the morning. i glance down and notice the speed i am going, but that's just because it's there.

the info the computers give you is kinda interesting i guess, but of no real use to me for commuting. i would encourage you to ask what it is you really need a computer at all for? it's useful for figuring out new routes and training rides, but commuting? kind of a mystery to me.
