Ok, I have to say... I was a hater, and now I'm a lover. I had the 3d and this phone side by side today... a friend's 3d and my Photon. It was in bright sunlight, no shade. The Evo 3d was no match for the sun. The Photon was like a beacon.
Any problem I had with this display I've now chalked up to extreme nerd pixel-peeping. You have to put the two phones side-by-side to see a difference, and even then the difference is really subtle.
But here's the difference... you put the two phones side by side and compare other features, the Evo 3D loses in practically every category (at least for me, which is why I took mine back).
Battery life, application storage, speed, the car and hdtv docks, the future laptop thingy, many useful additional features, bluetooth signal without having to turn off wifi, 3g and wifi strength and speed, call clarity, better auto-brightness, no over-bright lights behind the bottom buttons... heck, I could go on longer.
So all you crazy anal geeks feel free to choose the inferior phone for the subtle differences you see like "more life" or perceived "zing" in the screen. I've learned to look at it differently, and the screen is now beautiful to me. Take 'em out in the sun, too... if you want to have some fun.
