Hey! I just bought this mbpro model and I'm still on time to change it. Someone can tell me the main difference between these 2 models? I work mostly with adobe after effects and final cut pro, so I need the better and faster processor. I understand both are great, but I still don't know the advantages of the flash storage. 1.
