Good point about the old days when hard drives were small and every little bit of space was needed. Now that I have a really HUGE hard drive does not mean I keep everything either, you STILL need to clean house from time to time.
But I don't worry about storage anymore, it is unlikely I will ever push the limits of a 600 gig hard drive.
Well, that IS possible if I keep recording TV programs and never delete them. So I keep the Media Center recorded programs cleaned up for that reason.
