The rear housing looks virtually the same and we’re looking at an iPad mini with cellular connectivity here as you have the top of the rear shell of the device covered with a strip plastic, a feature designed to allow better signal throughput.
Speaking of unchanged design, we are not seeing anything new. The separate volume buttons, the rear camera location, the stereo speakers on the bottom and the new Lightning port are all where they were in the original iPad mini.
The leak looks credible and we don’t expect Apple to change the design of the new iPad mini this year. There should be other important changes, though. With Google upping the ante with the affordable Nexus 7 offering a stunning high-res display, Apple is now basically forced to put a ‘Retina’ display in the iPad mini as it just won’t look competitive, so that’s one huge improvement we expect to see. The usual hardware upgrade should also be there. What else do you expect of the 2013 iPad mini?
