original iPad mini featured a 7.9-inch screen with a resolution of 768 x 1024. This worked out to a pixel density of 162ppi, half of the 324ppi available on the Apple iPad mini 3.
As we say goodbye and pay our respects to the OG iPad mini, we can’t help but take a look at what has happened in the marketplace since its release. Originally, there was great concern that the 7.9-inch tablet would cannibalize sales of the 9.7-inch Apple iPad. Piper Jaffrey analyst Gene Munster even put a figure on this, predicting that the new mini would reduce sales of the full-sized iPad by 1 million units. But at the time, no one could foresee a 5.5-inch iPhone phablet that could cannibalize sales of the iPad mini.
