I sold my three year old 15" MBP a while back to buy an iPAD III when it first came out. I like the iPAD as a traveling entertainment device and as a decent substitute for a laptop for reading and responding to email, but I: cannot abide by its clumsy applications for word processing and editing, and I don't much like the IOS file system. So, I'm going to sell the iPAD soon, and buy either a 13" MBA or a 13" rMBP. The prices for what I want aren't that much different. My real question is over the screen and how large and sharp the letters in a word processed document are at the native resolution on each. I'm not close enough to an Apple store to put the two machines side by side and make my own comparison, so I am hoping someone here has done so and can clue me in as to what to expect. My fear with the rMBP is that its 2560x1600 native resolution will render letters on the screen sharp as a tack but really tiny, and that the 1440x900 native resolution on the MBA might not render as sharply but the letters will be a little larger. I was more than satisfied with the screen resolution on my non-retina old 15" MBP. I don't play video games. I do like to watch movies on the screen when I am on a commercial flight but, again, my old MBP seemed adequate for this. The dimensional specs of the MBA and rMBP are so close, I really can't use them to make a decision. So, it really comes down to the screen on these 13" laptops for me. I wish there were a way for me to see the qualitative differences on line, in re: what the screens look like. Suggestions? Thanks!
