Personally? I love the name, Wii. It's as everyone else has been saying, the name stands out... It's creative and has meaning to it. Unlike the "Revolution" that, while serving a point, seemed to be bland.
When I heard of it being named the "Revolution," I thought they were aiming to be like the rest... but upon changing it to Wii, you could see this system isn't going to be another one of those systems in the line. It has creative functions, original control system, and shamelessly... ? I can't wait for it.
