i guess I'm a weanie too. I've got the same set-up without the cadence thing. I've got about a 30 mile commute and it's really nice to know how much more or less work i have to do to get to my office on time.
I know it's not aesthetically pleasing, but it keeps me from getting yelled at work and without the bike mount and all the wires the stupid transmitter doesn't get in the way.
