I recollect one of the papers I reviewed for Telecoms Policy looked at
diffusion, but
not sure if comparative rates were used.

I also remember an economics paper at TPRC, where adoption rates of
different consumer devices (not quite new technologies, certainly not
since the invention and application of the semi conductor / integrated
circuits)) from the basic telephone onwards.

Naturally I don't have anything to hand - but you might be able
to locate these.

Best wishes
