Iíve been wondering about using a Bluetooth adaptor so I could use my Boom with e.g. a Google Hub.

The disappointing thing is I would need three power sources (AFAICT).

The Echo Show has audio out so I wouldnít need the Bluetooth adaptor.

I have a couple of unused tablets i.e. Nexus and iPad but I donít know of an elegant way of using these as UIs for the Boom - too much touching required.
