also about how much is 5 gigs?
About 5-1/2 hours of "HD" video from YouTube. Or any video from Netflix.
Over 80 hours of high quality streaming audio.
Video is the big one. Unless you're doing PC-level downloads of other stuff, you're probably ok.
They really need to stop calling this "unlimited"... when you admit there's a limit, you just sound stupid also saying "no limit".
