It is indeed exactly the same ppi as the 3GS, but the effect will be different because you're focusing on a wider array of pixels overall, from a greater average distance. Here's a pretty good article about it: http://www.tuaw.com/2012/03/01/retin...oing-the-math/ And as a nice bonus, there's a spreadsheet link in that article that has a row dedicated to the iPad mini. What's the "closeness to retina display" for the mini? At a distance of 16 inches away, 76%. This is compared to 61% for the ipad 2, and 123% for the ipad 3/4. Spreadsheet: https://docs.google.com/spreadsheet/...=0&output=html So accounting for average viewing distance, the ipad mini sits squarely between the 3GS and the 4/4S/5 for perceived sharpness. So I have some hope this this thing will be acceptable given the advantages in portability.
