The newly-released iPod classic has a serious design flaw that very few people are aware of: the metallic silver back half has been re-designed to prevent it from being removed. On earlier iPod models, like the previously-released 5th Generation Video iPod, one could separate the two halves using a do-it-yourself iPod battery replacement kit or, in a pinch, a metal screwdriver.

The concept of music players really had a facelift with the arrival of iPods. The portable media players designed and marketed by Apple Inc. named iPods were launched in October 2001. It was the result of the hub strategy of Apple Inc. that paved way for the entry of iPods. The company while dealing with various manufacturing of various electronic gadgets felt that the existing digital music players were "big and clunky or small and useless" leading them towards the production of Apple iPods. It took more than a year to get the Apple iPods to get developed. Apple iPods were launched with the catchy caption "1000 songs in your pocket," that was widely accepted by the music lovers around the globe.

Apple iPod Classic plays music files in various formats like AAC, eAAC, MP4, AIFF, WAV and audible audiobook.
