#1 to eliminate the need of adapters or a separate console, and the fuss of getting Famicom to show up on your TV or a touchy adapter that might reset your game at the slightest touch.

#2 to offer a cheaper solution to top loading NES by eliminating the blinky problem. A new 72 pin connector may be faster but they do eventually wear out because the contacts in those kind of connector flexes a lot more than a regular connector.

#3 be able to use your favorite NES pad as Famicom console's typically hard wired.

#4 because I have way too much time!

@NESCollector: you're thinking of wi1ykat. Slight difference.
