I suppose theres only one way to start this review, and thats by looking back at last years iPad mini review. In that review I had a section dedicated to the possibility of an iPad mini with Retina Display. The low resolution display and slow SoC were my only two real complaints about the first iPad mini. I listed a bunch of options that Apple had for the mini going forward: Apple has preferred outright quadrupling of pixel count (2x in each dimension) to create a Retina Display. With the mini's display using a 1024 x 768 resolution, this option would give it a 7.85-inch 2048 x 1536 panel. That would be the same resolution as the iPad 3/4, but in a much smaller display giving it a pixel density of 326 PPI (vs ~263 for the iPad 3/4). Apple could do this, but it would then need to make all of the same changes it made in going to the iPad with Retina Display, primarily the introduction of a larger battery and much larger SoC. The bigger battery is needed to drive the more powerful backlight, and the X-series of SoCs is needed to actually render the UI and games at such a high resolution. Both of these things would increase the size and cost of the mini, which would make it distinctly un-mini.
