Prepaid cell phone

If you were given an option to choose between prepaid cell phones and post paid cell phones, which one you will choose?

For me, definitely I will go for the prepaid cell phones. It's more easy and no hassle. What I am trying to say is with prepaid cell phones, I will not be bothered with any commitment or any contract at all.

Other than that, it is more cheaper ... don't you think so?
