iPod Touch 6th Generation
With a quick glance at the iPod touch 6th Gen models and the previous iPod touch 5th Gen models, it would be easy to confuse them for one another, but the iPod touch 6th Gen is a very different beast internally.
The iPod touch 6th Gen models each have a 4" (diagonal) widescreen multi-touch IPS "retina" display with a 1136x640 native resolution (326 ppi), dual cameras -- an 8 megapixel rear "iSight" camera with LED flash that can shoot 1080p video and a front-facing 1.2 megapixel "FaceTime HD" 720p camera -- and support for Bluetooth 4.1, and 802.11a/b/g/n/ac Wi-Fi in addition to the expected AirPlay, Siri, music, photo, video playback, and iOS app functionality.
Internally, this model is powered by a 1.1 GHz dual-core A8 processor and it has 1 GB of RAM and the option of 16 GB, 32 GB, 64 GB, or 128 GB of flash storage. Battery life is an Apple-estimated 40 hours of music playback and 8 hours of video playback.
