I still have powerboost with Charter although I have NEVER seen why powerboost was necessary or even cool. All it has ever done is mess up speed tests when trying to figure out connection issues!
What good does 5 seconds of powerboost do when you're downloading some huge Linux iso or something similar?
I mean, who needs a powerboost to download flash player, or Firefox/Chrome or just about any common program?--
The Firefox alternative.
