Today, Apple surprised everyone by announcing the iPod touch is getting a better-late-than-never hardware refresh just in time for the summer months.

The new iPod touch retains the 1136-by-640 (326ppi) 4-inch display of the previous generation, but upgrades the internals to use an A10 Fusion processor for running iOS 12. The quad-core A10 was first used for the iPhone 7 and 7 Plus, but also made its way into the 2018 iPad ($249.00 at Amazon), and it's a major step up from the dual-core Apple Typhoon chip powering the old iPod touch. You can argue it's an old processor, but there's only a low resolution display to deal with and the upgrade allowed Apple to unlock augmented reality experiences as well as support for Group FaceTime.
