OK... here's a quick comparison between SGP Steinheil AF and Powersupport (PS) antiglare.
I put both of SGP AF and PS antiglare on a single iPad - on the left is the SGP AF, right side is the PS antiglare.
--------------------------
--------------------------
100% zoom in on an icon. See the difference in the text. With PS antiglare (on the right) you can still see the pixels, SGP AF just blurs them away. You can imagine how much difference this will make, especially you're reading a PDF/ebook.
I think PS antiglare is the winner here.
