As others have said, batteries and recharging. Batteries die after a period of time.
bluetooth has a short range and if everyone were using it you'd have serious problems with the signal. Imagine everyone on a bus or an airport in short range trying to use their speakers, keyboards, ect all at the same time.
Are they going to start encrypting your Bluetooth signal as well. Wireless means less secure. Trade-offs you have to consider for something with no benefits.
you still avoid the issue of tech moving inevitably forward.
