Can someone tell me one reason why docks can be better than airplay? I can't think of one.
One word: Nightstand. If I'm travelling, I'd like to be able to listen to music, but I'd also like an alarm clock and can't expect the hotel to supply one. I could carry speakers and an alarm clock, or I could just carry a travel speaker dock (currently Gear4 StreetParty).
These are not exactly portable, so not for me, despite the better sound quality.
