>2) I'm actually still not really clear what the advantage of a retina display is. Maybe it's because I haven't been able to use one for a significant timespan, but I just don't get it. If there was a way to clearly and easily illustrate why a 13" display benefits from retina resolution, I'd really appreciate it.

How good is your eyesight? Honest question. The difference is night and day for me and I wonder how I lived with that blurry thing for so long.

Not very good, honestly. From what I've read, switching to a higher resolution wont really give me more work space, just make things more crisp, but I'm not sure how significant that would be for someone who wears corrective lenses already.

Maybe I'll look for some kind of 1:1 13" comparison...

I have terrible eyesight (somewhere between legally blind and failing a drivers' license vision test) and I find my eyes are usually less tired at the end of a day working on my retina MacBook than they were after a day of using my old 1440x900 13" laptop.

Smaller text is more legible, and larger text is less jagged around the edges so both seem to be less of a strain on my eyes. My thinking is that the sharper the image displayed, the less work my eyes and brain have to do to fill in the gaps.

This could all just be me subconsciously trying to justify the purchase (although I have no regrets about it) and obviously YMMV so I'd suggest going into a store and doing a side-by-side comparison using an application that has been updated for the retina resolutions.

If your vision is correctable to 20/20, you should be able to appreciate high res screens. If you have other issues (cataracts, macular degeneration, etc) that's a different story.

It makes things crisp enough that those higher resolutions are practical. Sure, you can turn your font size down low with a low res screen, but you rapidly get to a point where the characters are harder to distinguish. Not so with the retina screens. Really you just have to see the difference. It's striking.

I wear corrective lenses and I can see precise visual detail still. And my prescription is -8. It's the same difference between a retina iphone and a non-retina iphone. You'll see more details in your photographs. Denser text is more readable and so on.
