I'm surprised it made such a big difference to you. I went from the 13" Air to the 11.6" Air to the 13" rMBP and the 12" rMB. I think the 12" screen is the best one.Well, I've decided how I feel about the screen.
It's too small. The MacBook is going back.
Which is a pity, because I really loved that keyboard.
It is but some people don't like to sacrifice the larger screen size. They should have made the Macbook an inch bigger so the screen equaled to 13 inches but still had a smaller chassis. (Though I believe the MBP and MBA are 13.3 inches)
At 12 inches the MB is actually only .4 inch larger than the MBA 11, which is actually 11.6 inches.
As I have learned the MBr should only be compared to the MBA 11 and not the MBA/MBP 13 cause it's a different class of computing due to the size.
That's not entirely true. the MBA has a 16:9 screen while the rMB has a 16:10 screen. So there is more vertical space on the rMB.
