I have worked this out using the following "rumoured" dimensions.
4:3 aspect ratio
7.85" diagonal length
1024x768 for standard resolution.
2048x1536 for retina display.
The iPhone 4/4S ppi is 326
The iPad1/2 ppi is 132
The new iPad ppi is 264
Taking the aspect ratio and the hypotenuse (diagonal) into account, with a bit of trial and error I have worked out that it would be 6.28" tall, and 4.71" wide. (the screen)
Therefore the area of the tablet would be 29.5788"
So lets assume first that it has the same 1024x768 display as the first two iPads. This gives a diagonal pixel resolution of 1280. (Pythagoras) 1280/7.85 gives a ppi of 163, which is more than the original iPad and iPad 2, and clearly less than the new iPad.
But, if Apple decides to go for the retina display, (assuming it is 2048x1536) then... Diagonal resolution is then 2560, divided by 7.85, gives an amazing 326 ppi. Equal to that of the iPhone!
Basically, If apple equips this elusive device with a standard display, it will still be sharper than the iPad or iPad 2. Holding them next to each other for a comparison will show that. BUT. if they stick a retina screen in there... Then it is in a whole different ball park, I have held my iphone next to the new ipad and while difficult, you can tell that the iphone has more pixels crammed into each inch. and doing the same thing with a retina display ipad mini against a new ipad, will show that it is clearer and has the same pixel resolution of the iphone.
Personally, as someone who is in want of an iPad, i love the idea of an iPad mini and will get one regardless (IF it is released) But im glad to know that even with standard resolution it will be better than an iPad 2. Of course this is all entirely speculation and is likely completely wrong, but i would like to see apple release a Mini iPad.
I hope this helps anyone...
