Little Susie does homework, checks on her Webkinz, and downloads some Hannah Montana songs. Billy does his homework, plays WoW, and downloads movies (and maybe Linkin Park albums if he's feeling angry). Mom and Dad work from home sometimes, download the shows they miss while at Susie and Billy's sporting events, and chill out with some Halo on Xbox Live. All on top of web browsing and e-mailing photos to Grandma. 250GB is a pretty high cap, but I bet even an ordinary family could go over now and then. Perhaps targeting users who consistently use hundreds of gigs is reasonable, but an overall cap seems pretty silly.
