Very neat, however probably not useful to most people considering the console is rare and collectible, to increase storage size would probably require fine soldering, and there's many devices you can easily obtain for emulating NES well (DS with a flashcart, PSP, most Android phones + a cheap bluetooth controller or Wiimote, a 3DS.. I could go on).. Although I would like to see if anyone could do anything REALLY weird with it, like dumping the firmware and porting its recreations of the G&W games to other consoles, or finding a way to use it as a wired controller for something. Incredibly unlikely, but it's fun to let your imagination run wild with weird hardware like this.
