Sorry, but I'm bewildered by his attitude. So you use a device, quietly and unobtrusively, while he watches his choice of TV (which I'm guessing he knows is not your choice). What exactly is he objecting to?
Like muffin, this is a genuine question - I'm struggling to think of a possible reason to object.
I was chortling to myself interested to read he experiences difficulties when out alone due to his refusal to have a phone.
