Why is There an HP MediaSmart Server In My House?

If, a few months ago, anyone told me I'd eventually have an HP MediaSmart Server in my house, I would have laughed them right out of the room. 

"Me?  Why would I EVER want something like that?  I build my own Windows PCs, Linux file servers, and I even already have a network storage array, sitting happily in my basement, loaded with MP3s, videos, photos, and random documents we do not store locally on any of the desktops in our home.  And speaking of desktops, we have multiple laptops, Windows and Mac PCs, so I'm fully capable of supporting a complex, heterogeneous and sophisticated environment, right?  Why would I NEED a server dedicated to my media and backup when I already have these things already, right?"
