I have a Macbook and an iMac. For a number of reasons, I might drop the iMac and go w/ just the laptop. However, if I do that, I might also want to move up from the macbook to a pro. Here's a silly question, though: are the speakers and audio on the Pro much louder/clearer than that on a MacBook. I play a lot of music through my iMac, and if I got rid of it, then I'd really be losing something, as I think the audio on a macbook is pretty weak compared to the iMac. Are MBPs much better than MB? Are the comparable to iMacs?
