NES in a light gun?

Seriously?  Come on?  Though this is totally geeky-to-the-tenth power, there are so many other more compact methods of getting your 1985 8-bit freak on.  Like, playing Roms on a Pocket PC, DS, PSP etc.  Wonder if it functions as a Zapper so we can get our Duck Hunt, or Hogan's Alley fix, doubt it.

edit:  After further reading on the forum it appears that the light gun has full Zapper capability.  It now earns my full geek approval.  :)
