Some current implementations are nice (Score 0)

I agree that not everything should be wireless for all the reasons posted already. But I must add my vote in favor of ease of use items like wireless keyboard and mouse. Yes you do have to give them power somehow, sometime but its not inconvenient at all and unlike an early post its rarely "gone dead at a bad time" and then its because of my neglect in changing batteries I knew were dead for days and hadn't changed. I like to avoid carpal tunnel issues by typing with my keyboard flat in my lap on my couch. With a wired keyboard this would be all but impossible or at the least involve alot of cable to tangle in. Just my bit.
