So, random question. If you were to use a retina display (you know, the pixels are so small you can't see them), wouldn't you have no need for antialiasing? I feel like this should work as long as your graphics card can game at the full resolution of the display. I'm no expert though, so let me know what you guys think.
The reason I'm wondering this is because this should theoretically lower the amount of rendering power your graphics card needs (sure there's more pixels but it doesn't have to edge detect, etc.)
