To be honest, the real problem with betamax was that Sony never thought about longer tape lengths. They just designed a cartridge and then got in trouble when they had to catch up with VHS when VHS offered longer play time. People wanted to record a football game when they were away and you just couldn't do that with early Betamax. And even later on, VHS stayed supreme in playback length. Even though video quality was never as good as Betamax. I guess this also goes to show is that most people don't care about the quality of a device but the usability of a device. Which brings us right back and why people would want to use bluetooth audio even if it is a sub optimal experience.
