giggles, guffaws and catcalls?
I'm not sure what luddite community plays host to the Reg Hardware offices, but where I live bluetooth headsets (both the simple phoning type and the stereo music type) are very common.
And don't underestimate the bluetooth in cars option either - there is no other technology that even comes close to offering the functionalities: my previous car radio could play carkit for my phone but also accept music streaming over bluetooth. My bluetooth mouse doesn't need a (larger or smaller) USB dongle to work with my laptop. I don't have to get my phone out of my bag if I want to surf the web on the move, or take a call in the car.
I think bluetooth is already a major succes. It's not perfect, but it's ubiquitous, and if (as suggested above) it remains faithful to the concept, it has a lot of life left in it.
