Despite being on the list of devices that will be compatible with the forthcoming iOS 9, Apple on Friday quietly removed the original iPad mini from its online store, leaving only the second- and third-generation devices for sale as new. The company is still offering the original 7.9-inch device, but only as a refurbished unit now (starting at $209, $40 off its most recent retail price). The first-gen iPad mini was introduced in 2012.
