At my house we do the same. Everyone is always online doing something, whether is playing music, watching movies or doing homework. We have gone over our data a few times so a couple of days ago I called Comcast to find out how much it would be to change it to unlimited and I was told it would be an additional $30. I haven't changed yet because the representative told me that it's not every month that we go over so paying the $30 was not worth it. Now I'm on a mission to keep track of the data for the next few months so I can decide whether to change or not. :-)
