Those dongles you mention run about $100 each.  That GPS cable is a  
bother, but it sure isn't $100 worth of bother.  If you find a module  
that doesn't require you to implement the Bluetooth stack, it's still  
at least $50 for the component.

Bluetooth is so obscenely complex and expensive, you apparently need  
a large development effort so you can use a cheap BT radio and  
implement the stack in house, then sell a bazillion of them to recoup  
the development costs.

Oh, and that bluetooth peripheral needs power sooner or later, so you  
either change/charge batteries, or you plug it up.

I was excited about bluetooth until I gave a serious look at  
implementing it with my APRS rig in the truck.  It doesn't look so  
good anymore.
