I saw this last nite and was thinking for sometime 'What is this actually useful for as far as consumers are concerned?'. Sure its nice to show pics and movies, but its only a little wow factor on XMbox 360 + Media Centre.
But then it hit me - DJ decks. This thing would ROCK as a DJ deck. Come up, put yr wireless device (like Zune) on, drag songs, scratch mix, do all yr crassfading and equalisation - VERY KEWL!
Now I want one ;)
