If a provider wants to sell me a 384kbps line, they should offer 120 gb per month. If they want to advertise a 20 mbps line, they should sell me 6.3 tb per month. If they can't provide the capacity, sell me a slower line and I'll be happy when I get bursts of speed. Regional monopolies should be compelled to have transparency in pricing.
Also, why should the quota be tied to the speed? When I want to download a movie, I want to download it as quickly as possible, but that doesn't mean I want to max out my bandwidth continually.
There is not enough core bandwidth to maximize every edge connection out there -there never will be. That's the nature of packet switching and shared connections.
Should ISPs have to be more honest, and more flexible about what types of services they offer? Consumer expectations are changing, and ISP offerrings should reflect that.
I think so - net neutrality is important (for the internet as a global community in and of itself - not just for the "consumer"). The internet grew to what it is based on cooperation - lets' not stop now.
More transparency in regard to caps and utilization would be good, but I don't think metered billing would be the end of the world (provided that it generally approximated what people are paying today).
