That's like saying you want petrol stations to start closing down, so that manufacturers hurry up with electric cars. The logic is sound, but in the meantime it would be just bloody inconvenient to drive miles to a nearest petrol station while you still haven't got an electric car.

I want wireless headphones too, but I don't want to use adapters with my existing(and very expensive) headphones that I have right now. More importantly, having a headphone jack does not stop bluetooth headphones from working.
