i haven't technically played mine in a couple months, but only because it broke so it won't play discs. i still play my VC games occasionally and i use the internet channel constantly cause i don't have a real computer. i plan on getting a new wii soon so i can start playing discs.
and in my personal opinion, the only reason people get bored with the wii is cause they're buying the wrong games. if people buy the good games and avoid the shovelware then you don't get bored of it. trust me on this, i have a PS3 and if my wii could play discs then i'd be playing it more then my better system. you just gotta buy the right games for you.
