Anecdotal I know, but I've noticed over the years that most Windows laptop users don't ever use the included Bluetooth adapter. Most wireless peripherals that I've dealt with end up having some kind of included USB dongle. Why is that? It seems strange to me that "premium" keyboards and mice use their own dongle as opposed to the Bluetooth adapter which just seems to go to waste. Another example of this is my Bluetooth headset. I have a very nice Plantronics Voyager Legend and despite using Bluetooth to connect to my phone and old game console, I have to plug a dongle into my PC to get the headset to work with my PC. Can anyone comment on this? It seems like such a waste of a proven technology if many wireless devices don't even bother to use it.
