Cell phone service -- what is the attraction with postpaid plans?

With the advent of smart phones a lot of users want lots of data – unlimited these days – so they can use their phones to watch HD videos — and prepaid by definition come with a data cap.

There are prepaid unlimited data plans (prepay for a month of unlimited data). But most unlimited data plans (prepaid or postpaid) seem to have data throttling for very high users (some cell service companies have gotten bad press for having undisclosed or poorly disclosed data throttling).
