I've found wireless to be good and bad. Prior to my most recent wireless computer, I would periodically tear the wires when packing/unpacking the bike for travel. Not every time, but I ruined several wired leads that way. Last time that happened, I replaced with wireless. Now the only thing I'll occasionally get is some interference that causes the computer to suddenly go into hyper-mode and hence I'll lose track of distance. This seems to happen with overhead lines, electrified fence, some city streets and overhead tram lines. Nothing fatal, but then I'll just estimate the total adjustment and go from there.
