Remember a couple years ago when this whole "retina" thing didn't exist? It's not a huge deal... Enjoy your Mini for a year, works out to like $27/mo., then sell it back for >60% of what you paid and get the retina one, if they even come out with one.
But it does exist...and competitors offer it. The Nook HD is 240ppi led laminated.
This whole shut up and buy attitude is the reason why you don't have the option.
