Dana Levine for The Tech Block, on why the iPad Mini is great despite lacking a Retina display:
So there’s a problem with these retina displays that Apple is gradually rolling out on their machines – they are a nice-to-have, but not really disruptive to what we already have. When you look at disruptive technologies (as defined in The Innovator’s Dilemma), they typically enable use cases that their predecessors didn’t (such as allowing devices to be smaller or lighter). There isn’t actually any new use case that a retina display enables, other than being prettier. It’s not like visible pixels in any way diminish the functional experience.
A totally fair and valid argument, but it makes no difference to me. My eyes are so spoiled by Retina on my iPhone 4S and iPad 3 that it even makes me wince looking at my non-Retina 1280x800 MacBook screen. It’s as if being able to discern pixels has a psychological effect on me. My next Mac will be Retina; to go without is just too bitter a pill to swallow.
