Wow! 400Gigs....Daddy like! I am amazed at the advances. I remember my first Comp. A commadore 64 it was beautiful. I still have it, it had huge blocks that made up the ram. It was an awesome system. With a pure Dos based environment (I coded my first program in it). But anyway, yeah 400 gigs is alot. But like others have stated with the advances in DVD burning technology and things of that 400 gigs can be filled up rather easy.
