I'm sure this has been discussed before (and I did search and read through some posts) but you all like talking about this stuff anyway, right? Now that I have the new bike, I'm gonna need a cycle computer. Being a full-time IT geek, I'd like to have a comp that can upload to a PC so I can keep a log easily. What the advantages/disadvantages of wired vs wireless? I definitely want speed/distance and heartrate but do I need cadence too? Of course, I don't want to spend a fortune (~$150 +/- max). The Polar CS200cad looks good on paper but user reviews are all over the place. Should I just get a simple speed/distance comp w/o upload capabilities? What functions do you really use?
