I shouldn't have stopped by that Apple reseller, and I should have stayed away from that comparison table with a regular 27-inch iMac and a 5K Retina one. Wow, wow again, what was I thinking trying to make that Dell UP2414Q 4K monitor work with the nMP, and wondering whether that new 27-inch 5K screen from Dell might connect to the nMP with two miniDisplay cables... The Apple 27-inch Retina 5K future is already here, and (sadly) it's not the nMP. I sold my QC/32/256/D300 nMP + UP2414Q within a day and am now awaiting delivery of my Retina 5K iMac. It was nice knowing the nMP and following the interesting threads here, but I'm headed for the best consumer screen now, period. That's important for me, as I work mainly with text. Take care.
