Wow, my basic take on the Wii is this: it has a certain target market, the more casual and party type gamers. If you're not in that market, why are you complaining about the console anyway? Some sort of nostalgic entitlement? "Nintendo made the games I was raised with. Why don't they cater to me still?" Well, Mr. Whiny-pants, probably because you've moved on to things like GTA, Modern Warfare 2, etc. and Nintendo isn't trying to capture that demographic. It's not a personal insult to you, so get over it.
I like the Wii, it's fun and silly, but it's not the console I go to for my more "serious" gaming needs, that would be my PC and my PS2/Xbox (yes, the only "current" system I have is the Wii).
