Oh goodness, I'm the last person to defend bluetooth keyboards and mice. I can't stand them. Is it too bold a statement to claim that bluetooth, on the whole, has been a failure? Is that incorrect? A rough count in my head tells me that I've used about 15 different bluetooth devices over the years (phones, headsets, headphones, cars, and miscellaneous other products). I'd estimate that a total of 3 pairings have been reliable and usable. That's a failure in my opinion.

As RF keyboards and mice fell out of favor, I constantly defended RF as a technology.

Sorry to take this so far off topic again
