I have avoided clipless pedals like the plague up until now. I am riding strictly for fun and exercise, and don't think falling down is much fun. I KNOW if I get a set, I will fall a few times getting used to them. I also know they will let me ride further and faster in the allotted time, which IS fun. So. Are they worth it?

From what I have read, SPD looks like the system of choice. Is that correct? Is there any reason not to get a pedal that allows one to ride with or without clipping in? Other than weight, which is not a major consideration here. Any advice on shoes? I insist on being able to walk in whatever I get. Not for miles and miles, but at least into the quickie mart.

Second question. I've also avoided a bike computer like the plague for no real good reason. I think I will get one to see how much I really do ride next year. I'm leaning towards a wireless unit. Any suggestions on ones to choose or alternatively avoid?
