I'm not even going to try a wireless computer. I can see trouble from a distance. I do a lot of work with wifi networks and similar things. There are so many things to go wrong that just don't exist when you use a wired bike computer.

Believe it or not, I've been quite satisfied with no-name computers that I get from Chinese web sites, Amazon, and Nashbar. They have worked flawlessly. At this point, I kind of wish I had Cateye computers, because since the mounts are more likely to be available, I could put a mount on each bike and move the computer from one to another. That is one advantage of wireless computers, but that's not big enough to sway me to use a wireless computer.
