@Kowenicki: Ok, but you actually got it all wrong. The controls aren't the reason for Wiis success, it's the software like Wii Fit, Wii Sports, Wii Play and Wii Music. Not to mention games like SMG, Brawl, MP3, TP and MKWii. The control method do play its part, by making the game more accessible, but that's not the driving force here, just look at the DS, its sales didn't pick up until Nintendogs, Brain Training and NSMB.
Anyway, where do they lack in quality? If you are talking about Wii Music, keep in mind that it's one of the first games that have been in developement for Wii and has propably the longest developement time so far. If Nintendo would want to "whore out" with their games, they'd be putting out games like "Dogz" and "Catz" or "NHL XX" every year, not making games that have taken 3 years of developement (like Wii Music). Besides, these "whored out" games, Wii Sports, Wii Fit, Wii Play, Wii Music, all target different audience (of course, there's overlap), so they aren't actually riding on another games success.
Your statement about selling your Wii because of games like Wii Music didn't make sense, because the more "traditional" type of games still keep coming.
And lastly "i don't like it" doesn't equal "quality".
