The iPod touch exists to be used by waiters, warehouse staff, delivery persons, and anyone else whose employer wants them to use an iOS device as a handheld on-the-job computer. That’s why it just got an update, and it’s probably why it hasn’t — and never will — change size or shape. It is a utility computer. Making it an all-screen, buttonless iPhone-lite is pointless. Adding Touch ID is equally useless when it is used by multiple people.
But that doesn’t mean it isn’t also a great device for everyone else. If you need a utility iOS computer, then you should buy it. Musicians are one great example of potential users. Let’s see why the iPod Touch is still great.
