I'd love to be able to pay reasonable data charges per megabyte. The problem is that overages are currently insane, compared to what it costs for fixed monthly rates.

Agreed. This exists for the same reason the costs of text messages are so exorbitant: lack of competition.

Doubtful. I think both are too expensive, but both data and SMS plans are only able to be priced where they are because of breakage[1].
