Actually at the moment with the amount of info we have so far, to use natal to interact with your TV or 360 interface is the only reasonable purpose i appreciate and was thinking about right at the beginning (minority report comes to mind). It would be cool to control my devices just by hand waving and language.
But i still have concerns how natal will work with games (much more information needed!).
