Not to mention wired computers are much more reliable. Cost wasn't an issue for me, I owned three of them! But they don't last more then 3 or 4 years. I don't particularly like cell phones either because none of mine have lasted more then 2 years, but I need a cell phone so I put up with the BS, I don't need a bike computer, it's hobby and thus a want not a need, so I don't have to put up with the BS.

Speaking of rain, I've been in torrential rain fall many time and never had an issue with the wired computer stopping, even the one that I had that was 18 to 20 years old.

Cateye had a poorly designed bracket (not sure if their new stuff is designed better), I did toss my wireless computer on rough roads a couple of times but I was able to find it. The Sigma, while wired so it won't go anywhere anyways, the twist and lock bracket secures a lot better.
