I'm quite surprised that this issue is not stressed enough. We still don't have(avb is still under development) a solution for stereo/multichannel audio via wifi, let alone bluetooth. I understand the jack is old but why do we replace it with an inferior technology? I expected more from Apple not just to trash quality for convenience.
