Experts from a teardown firm iFixit examined the internals of the new fifth-generation iPod touch. The teardown offers a look at how Apple has managed to pack all of the details into a body, which has 20 percent less volume than the fifth-generation iPhone. The iPod touch lacks cellular communications technology and carries fewer details, which are consolidated into a handful of parts. The battery and logic board are smaller than in the iPhone 5 and they are arranged in a top-and-bottom layout unlike the side-by-side layout used in the iPhone.
