So, I have debated back and fourth about this. I have come to the conclusion that the 15"MBP might be the one for me. I will miss the lightness, and speed of the SSD on the Air, but I won't miss the screen size. Those two inches make a huge difference. But what may make or break my decision is if the screen. I have a 2011 13" MBA and the screen just does not seem as good as my friends 2009 MBP, even. Are the screens different between the 2011 MBPs and MBAs? Are the actual screens different types? Would you suggest doing the hi-res upgrade?
