Hey Guys. I have a mid 2010 macbook pro. I am looking to shell some and buy the new 13" retina, with i7, and 512ssd. Question is, is it time for an upgrade or I would be disappointed? Also, since I make music, and have seen a review that says the speakers are way better.. Will I feel a difference in that aspect as well? I understand that the Ram is not changeable, so I would probobly get the 16gb... Its a pitty that I can't upgrade by myself. How about the SSD. Is it upgradeable? Last but not least. Anyone who has purchased this MBP, do you have any cons or issues to report? Those are my questions so far... Thank you so much!
