Quick question guys... How are the speakers on the MacBook Pro 13 Retina? I saw an audio comparison between it and that Dell with the really thin bezel and I was pretty disappointed with the Mac's speakers. It got me thinking of buying one of those tiny Bluetooth speakers. Then again I figured I would ask here first. What are your opinions on the speakers? I know th they aren't going to blast the room away, but are they...passable?
