I know a couple of people who've said, hands down, they'd take a Mini over an iPad 3. I would, in a heartbeat (and probably will next year, for 'testing') and I love the Retina displays, I just don't think you miss it that much with the iPad Mini unless you're reading, you have excellent eyesight and you hold it really close. I know some people will inevitable go "you can SEE the pixels, right there, there's a pixel"…
Then I pulled out my old nexus one to compare how crappy it would look now. As it turned out I could not tell a difference. the 800x480 screen already is dense enough for me to not see any pixels.
Confirmation bias is a bitch.
