Hi, I plan on purchasing a rMBP when Mountain Lion is out, but I would like to know just how much of an improvement the speakers are. None of my Apple resellers have the rMBP on display so I can't test it for myself. Does anyone on here have a recent unibody MBP and can compare/describe with a video or description how much better they are? It seem every other aspect of the rMBP has been investigated, however I haven't found any thread that talk much about the speakers other than they are "better". BTW, I'm not a audio guy, just wondering Thanks!
