But that's different to my point, in two ways. 1) I was talking about cost not quality (c.f. "wireless would have gotten better even if"). 2) I wasn't arguing about whether it would get better or not, but the rate at which it happens being changed by removing the jack (c.f. "would have gotten better even if we did not remove the headphone jack.")
