...Pretty much all I do is watch TV shows and movies over Netflix/Hulu/whatever, and download Steam games. Along with normal browsing and file downloads of course.
I don't even go out of my way to download a ton of stuff. So it's not all that difficult.
I have the HDTV package so I watch TV on TV. I suppose watching Netflix all day would get you there. I am tempted to dump the TV. There is never anything on.
