The "official" name doesn't matter to me, I will call it anyway I want. Most people at my school and free time don't even know what Nintendo is, nor do they know the SNES or even NES.
About the "Wii", in german it's "Wie" which can have be alot of different meaning, for example:
-"Eh?" (That's really what my dictionairy says)
or -"how", "as", "un-/like", etc.
Not that I like the name, but I don't like "Game Cube"(even if more fitting) either.
Why not calling it the "Nintendo Eh?"? That's what most People will say anyways.
