Since football is coming I've been debating wether to activate my ipad to a plan. Got these questions:

HOw does att prepaid plan worked?

Do I really pay as I go?

Whats the difference between prepaid and postpaid?

With prepay you start and stop your account direclty on the iPad. You pay for a month and use it. It automatically renews unless you stop it.

Post pay is just like your regular phone bill. You manage it the same way, by contacting AT&T service, or through your account website. You pay at the end of the month.

Here is AT&T's answer site where you can find much much more than I can remember off the top of my head.
