At its October 22 event in San Francisco, Apple has surprised no one by releasing an iPad Mini with Retina display. It is available to preorder today, with a release date "later in November." The base 16GB WiFi iPad Mini will cost $400, with cellular models starting at $530. Like the iPad Air, it will come in either space gray and silver. The original iPad Mini (without a Retina display) will continue to be sold, but starting at a lower price point of $300.
