Damn sure i won't buy it if it's NOT retina display, but i will if it is... I still have my first gen ipad (only non retina devices that i have) and it sucks a** compare to all my other retina devices... I can't go back!!
I appreciate your enthusiasm. I have the rMBP and 4S, and their displays are amazing. Compared to my 2011 MBP, the rMBP does have that amazing detail. But I think it comes back to what will you use the device for. I plan on replacing my Fire with the mini so I'll be happy with whatever resolution the mini comes with. And, you know it's going to be good because it's from Apple.
BTW what do you think of the screen when you have to use your MBP?
