Black magic

This is amazing...it's a little black box connected to our internet and it not only stores all our "stuff", but allows us access to it wherever we may be (as long as there's wi-fi!)
So my iPhone can now access all our music and photos even when I'm miles away and if I want to store any new "stuff" I just press a magic button (or app) and it sorts it all out!!
Now that is magic (or clearly, I'm getting old, cos I haven't got a clue!!)
