Apparently nobody understands what I am saying. With the glass display on the Macbook Pro, it is a fact that a dab of water and a quick swipe cleans it good as new- no smudges, no anything. With the non-glass displays you cannot do this. Try it right now. Get a little water and the Apple microfiber and try. I guarantee your display will have streaks or smudges at certain angles (put it in sleep- you'll see it) on the non-glass displays. Do the same with a Macbook Pro and you will not have this trouble. The fact that I don't have to buy an extra cleaning product (just the Apple microfiber and a dab of water) to clean my glass screen = glass > non-glass display in my book. If you cannot replicate this situation and notice the difference, you are obviously not as astute as I am or as OCD as I am about my displays. That's fine, but the fact still stands. Search online and you will see that many people prefer the glass displays of the Macbook Pro over the Macbook Air/ Macbook for this reason alone.
