Mac users, I apologize in advance for a "crystal ball" sort of question. As I slowly migrate back toward the Apple universe for creative work I'm thinking about getting the 13 inch MacBook Pro retina. My question is: will it be sufficient for the next several generations of iPhone video editing as well as running LR CC? The high end 13" rMBP seems like a good compromise in power vs portability. Is it reasonable to hope that it will remain so over its hopefully long life?
