To a very close approximation ISP customers do not fully use their bandwidth. It seems silly to change pricing structures to cater to a tiny minority (less than 1%).
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).
