I have a wireless computer that I just put on the bike on Friday. I love it, works great, but I have never had a wired one to compare to. The install for a wired one did look harder (the manual had instructions for both), and I (finally) have bike pride for my pretty new bike, so it is nice not to have the wires running about the frame. The only problem, from my perspective, is that I can't really use it on the trainer indoors in the winter (the sensor and computer need to be 23-27 inches from each other), but I will go more on time then, anyway. The computer is a BIG help to me to see how I am doing-I am new enough to biking that I am pitiful at estimating time and speed. And I will poke along slower without the computer than with it- I just know that about myself. But I can see how, if I was fairly expert or was feeling pressured for performance, riding without it could be liberating and help restore some joy. But since they aren't cake to take on and off, I think I will stick with mine (plus, i am far from expert). I strongly recommed computers to newbies like myself, even if you think it makes you seem to "serious"!
