KISS.
I'd propose, for any plan :
Per GB overage: $0.25
Max bill: unlimited+$10
Obviously modify those numbers to where it needs to be....
....People want to know two things :
(1) How much a gig extra do I have to pay, and
(2) What's the worst case (max)....
When I put on my businessperson hat or my geek hat, I envision ideas like most of the other posts here today (including some of my own earlier ones), but when I don my John Q. Public chapeau, I see exactly what Guspaz just posted.
How CAN that be ???
Hmmmm....
