As I understood it, the point was for games which should be always-on. That said, A heavy gamer on a WOW-like game could be 120 hours a month, which would be on the same order of magnitude.
What I mean by fair price is that this is not an easy thing that they're proposing -- enough bandwidth and hardware to play a game. It may cost more than you would expect to deliver a high quality experience. However, the value to consumer isn't there for 83 cents an hour.
That's >1,500 a year PER USER for a typical business app
No way this is going somewhere at the current fare imo.
