Have to say, I agree with those suspicious of Bluetooth. Works well - except when it doesn't... and of course it doesn't explain why it doesn't. I'm sure it's a driver thing, but I've got 3 or 4 in the drawer I've discarded when no amount of killing & re-installing will get 'em to work.
FWIW I have a cheapaschips USB hub at the back of the desk with links to camera, phone, satnav already plugged in and dangling - I just connect the beast I want to use when I need to.
Why each manufacturer insists on a proprietory USB connector is another matter...
