You know, I've been thinking this for the past few days but Nokia really nailed the glare reduction on the 920. Without even noticing, I found that I have been mostly using my phone in areas where it is completely basked in light and I can still easily see the screen in full colors. This is literally in a completely different league from my fathers Iphone and Ipad or my mothers blackberry where I can't go anywhere without having to find an angle where glare isnt as bad.
I noticed that yesterday while walking outside in the sun. It's pretty amazing. The screen has a "super-bright" mode that completely over-saturates everything if you're in really bright light, but hell, it works.
