Yup, noticed it a few weeks ago. I'd been wanting to test it in the Sun and ended up going out as the Sun was just above the trees. That put it directly on the screen and I realized it was very readable. Looking kinda layered like the text was suspended before the back screen.
The MBA screen actually does quite well in bright light even when not directly shining on it. It is SOOO much better than my MBP from early 2008 ever was.
