Can anyone explain to me why Apple hasn't done the following? I refer to making OSX *itself* able to detect an AirPlay compatible device and allowing a user to stream the *entire* audio or video to that device, as if it were an external speaker or display. Instead they have picked a few (far too few) applications and allowed only those to stream content to Airplay devices. This seems utterly silly to me, and I really cannot understand what would be the advantage. I generally think Apple has turned way too much attention towards mobile devices and way too little attention on OS X lately.
