As I suggested would be the case when the iPad mini first came out, it's on track to becoming the most popular iPad, outselling the iPad with retina display, according to market analyst David Hsieh with NPD DisplaySearch. Apparently Apple had expected to sell some 6 million iPad minis in 2012, with most of those sales coming in the December quarter. But according to Hsieh, as reported by CNET, Apple has asked the makers of the display panel for the iPad mini to ship over 12 million of them for the quarter.
