Basically, the 2015 iPod got a brain transplant to keep it chugging along. Everything else about it remains unchanged making it an easy swap out for businesses that currently rely on the iPod, but a hard sell for most people.
The new iPod Touch is twice as fast as the previous version and will be able to run iOS 13; Its small size, thin body, headphone jack and old school iPhone-vibe will appeal to some.
Battery life isn't great; photos and videos are only OK and larger storage versions of the iPod Touch cost too much.
