I bought it because it looks good in my living room. The other consoles are just plain ugly! The Wii is a nice addition to my minimalistic home.
The blue light is awesome at parties too.
Another reason I bought it was the music in Everybody votes channel.
Why would anybody want to buy it for some other reason?
