Jeremy Horwitz, writing for 9to5Mac:

The original iPad mini has quietly disappeared from Apple’s web site, and is no longer available to purchase new from the Apple Store.

And:

Apple’s discontinuation of the iPad mini leaves the remaining iPads as a completely 64-bit family, all using either A7 and A8X processors rather than the iPad mini’s aging A5.

The oldest iPad you can buy has a Retina display.

Considering the massive change that multitasking is going to be for 10-inch iPad users, I wonder how quickly Apple will phase out the iPad Air in favor of the split view-enabled iPad Air 2.
