I'm screwed

Based on 5 minutes of monitoring ONE of the computers in the house, with nothing going but Yahoo IM, AOL instant messnger, Windows Live messenger, and  5 IRC channels on one server, I am going to use 165gb of my 250gb a month cap assuming no chatting, just logged in watching

8.7 minutes of watching google's doodle today, will use a GB

30.02 hours of 720p youtube (which isn't 720p, it's quite less actually) and you are at 250gb. Screwed. Screwed with AT&T
