I'm thinking about picking one up with tax return money. Do you use one? Share your experience, likes, dislikes etc. I had a garmin forerunner and it sucked. It was huge on my skinny girly wrist, uncomfortable, unreliable and generally disappointing (good thing REI stands for "return everything inc"). So I'm thinking that a computer will take care of the false gps readings that I got on the garmin. Things I want:

Something that I can mount on my stem (quill, I don't even know if that's possible)

Wireless

Heart rate (my garmin did not have this, so I don't really know much about this part)

Cadence?

Watts? I don't even know what that is or how it pertains to riding/training.
