I've never understood why mainstream ISP's and mobile co's do not charge per GB at a reasonable rate rather than offering an attractive bulk allocation of bandwidth.

For the same reason you have hosts marketing "ulimited" shared hosting accounts for $6 a month. It makes for good marketing. How many people do you think are out there paying $40 or $50 a month that check their email and surf a few pages each day?

They aren't going to make money off them on tiered plans.
