Battery life on my Garmin Edge 800 will allow almost 24 hr of riding. It is very easy to recharge. It has cadence, heart rate, maps, temperature, grade, speed and tracks my route. I don't think there is a wired computer that will do all that for a bicycle. Some smart phones will do speed and route but not cadence and heart rate. They also don't have wires.
I stand by my statement that "good wired" is an oxymoron.
Riding a bicycle is different than using a computer in the home. It is also different from using a computer while traveling. I don't have the luxury of connecting a cat 5 cable everywhere I go. I can get wireless internet most everyplace.
My Cateye Strada wireless has been very reliable and I have not expended the batter yet. It also doesn't do cadence, heart rate and routes. I also don't want ugly wires all over my bicycle.
Although I am a Geezer, I am not a dinosaur stuck with old technology.
