How is Traktor DJ for the iPad?

I know the Traktor DJ app for the ipad has been out for a few weeks now, I'm wondering how many of you have it and how useful it's been for you. I wouldn't really want to DJ mainly from the iPad, but I imagine it would be a fun way to mess around with mix ideas or to do track preparation when I'm away from home. I never really considered getting an iPad until this app was released, so it's going to be a slightly heavier investment for me... But this app makes me want an iPad.

Please read and use the exsisting popular thread for the app.
