Once Apple removes the analog connector, they also get to remove the Digital to Analog Converter (DAC), Op-Amp and other circuity that goes along with powering and controlling the analog audio output. This is interesting because all of these components now get moved to the dongle. This would be a great "Analog" system "Export" for audio developers and audiophile types who would then be able to put whatever DAC and opamp packages they want in their third party dongle. Unfortunately I do not see it panning out that way. I am sure Apple will have a stranglehold on interoperability with third party vendors for some time. DRM will also most likely control who gets to play in the Dongle arena.
