Although there are many differences, conceptually the iPod touch (5th Gen) remains very much an “iPhone without a phone” — just like earlier models — and Apple promotes it with a heavy emphasis on “fun.”
More specifically, in pursuit of said fun, the iPod touch (5th Gen) has a 4″ (diagonal) widescreen multi-touch IPS“retina” display with a 1136×640 native resolution (326 ppi), dual cameras — a 5 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 4.0, 802.11n Wi-Fi (both the 2.4 GHz and 5 GHz frequencies), Siri, and AirPlay in addition to the expected music, photo, video playback, and iOS app functionality.
The iPod touch (5th Gen) is powered by a 1 GHz dual-core A5 processor, has 512 MB of RAM, and has 32 GB or 64 GB of flash storage (a 16 GB option was added June 26, 2014). Battery life is an Apple-estimated 40 hours of music playback and 8 hours of video playback.
Unlike earlier iPod touch models, which have been black or white (or even just black), the iPod touch (5th Gen) models sport aluminum “unibody” cases originally offered in six different color choices — dark gray “slate” (which has a black glass front) along with silver, pink, yellow, blue, and red (which have white glass fronts). However, on September 10, 2013, Apple swapped the “slate” color for a gunmetal “space gray,” which also has a black glass front like its predecessor.
