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.
Interesting. But how is the ipad 3/4 at 123% of retina, when it's defined as retina? Shouldn't it be 100%? Of course retina is just a random marketing name anyway... But this report does illuminate what I suspect about the mini. There are times when I look at my ipad 3 quite closely...shorter than arm's length. At that distance, I think the mini will show its pixely retro face.
I think you're right. I really don't know how it's going to look until it's in my hands. I preordered just the mini betting that if I want to return it and get a 4, the 4 will be widely available because of the 6 month upgrade cycle. I checked the ship date for the 4s and it seems that theory is holding up.
Your links didn't work for me, how about this one. http://www.tuaw.com/2012/03/01/retina-display-macs-ipads-and-hidpi-doing-the-math/ Looks like both the links end up pointing to the shortened version, not the real URL. I could find the TUAW article but can't guess the link to your google doc.
what?!?? 123% means that the iPad 3/4 actually goes above and beyond the minimum ppi required, by 23% at viewing distance "d" at angle "a" , for the human eye to be unable to see an individual pixel. 100% is the baseline
Not sure if using 16" for the Mini makes sense. Its a smaller device, seems that you're likely to hold it closer. That would counteract the higher PPI making the % retinaness the same. I hope they've done something else to the screen to help. I don't normally see pixels but I've always thought the iPad1/2 looked extremely pixelated. The iPad3 was not a minor upgrade to me but a night and day difference. I have one on order. Will see if its any improved over an iPad1. There's something about the iPad1 that looks really bad to me. I can see the colors that compose each pixel. Looks very grainy. I don't notice it on my Macbook air.
Maybe. It was a night and day difference for me too... just trying to assuage my doubts here as I really, really prefer the form factor of the mini. There are indeed lots of other factors in display tech than pure pixel density. Josh Topolsky of the Verge made a note that the mini display looked brilliant despite its ppi; I trust his opinions. Only thing to do now is wait and see (literally)...
