The difference between 7″ and 7.85″ is everything

Here is a different take from Kosmatos on Tech on a 7" device from Apple that is more of an iPod Maxi as opposed to an iPad Mini.

A 7″ diagonal screen (7.08″ to be exact) just happens to be the exact size of two by two iPod touch retina displays. That’s a 4″ x 6″ display surface. An iPod touch screen has 326 PPI. The 7″ screen would also have 326 PPI just like iPhones and iPods. This would yield a resolution of 1920 x 1280. This resolution would be able to run current retina iPhone applications pixel perfect using the traditional 4:1 pixel scaling, like retina displays do with non-retina apps.
