iPod Nano now has a camera?

According to Apple's website, Apple is releasing the new iPod Nano, now equipped with a built-in camera. My question is: why does the Touch still not have a camera? Apple just likes to hold features back when they could very easily add them to their devices, just so they can release them one by one and call them new and technologically advanced versions.

The Nano with a camera seems like a waste to me. I can already predict that they would break really easily.
