250GB is enough right now, but in a few years it won't be. Lets hope a real unlimited ISP comes out.
It's already here, FIOS has no caps and they have true speed too. I have the 50mbs tier with them for $90 a month.
I hit the max speed anytime of the day, any day of the week for as long as I want. Unlike Powerboost which only boosts the speed for a very short time.
