Wow. I moved from 2009 13" to 2013 15" MBP a week ago. Liked the new machine and did not think much about the screen at all. Today I needed to do something on my wife's older (2011?) MBP. Holy crap...that old screen really is different. I was just not aware of it, even when I had my two machines side by side during the transistion. Okay... just had to share that for anyone thinking about it.
