Difference between iPod Touch and iPhone?

I know for sure an iPod touch can't call people (unless you download an app)
But what other differences is there?
Specifically the iPhone 5 and the iPod Touch 5G but I don't mind what you compare. Thank you.

Added (1). I have an android, fyi & I'm just wondering if its worth getting an iPod Touch

Get an android!

In addition to calling/texting people, the iPhone has a better camera and a better processor (the iPod processor is one generation behind).

Internet everywhere, faster with a better processor, can call, can text anywhere.

The iPod touch isn't as fast and the camera on the iPod touch is 5mp while on the iPhone 5 its 8 mp, not a big difference really, the iPod touch is a lot thinner and weighs less though. The iPod touch 5g will be about as fast as the iPhone 4S since it has the same processor chip so not bad for a 200$ device with no contracts.
