I'm sure we'll be able to see direct evidence for ourselves in a few days, but can someone tell me why retina displays are so important on a laptop? On iOS - I'm a huge believer. The clarity you have with a retina display is incredible. My eyes would get tired on an iPad2, but not an iPad3. I'd never go back. But on a laptop, we already have sub-pixel rendering and text smoothing. The OS takes care of that and my eyes don't get tired looking at a laptop screen. That makes me think that I won't be wowed by retina on a laptop when I see it. Too skeptical?
