The Wii... talk us into it...

Ok... talk me into a Wii...
I am leaning 75% towards getting it and have seen it a couple times but haven't bought it. The console and a couple extra items is more then we usually spend for the family on the holidays but I do have some garage sale money that I want to put towards it. As you can see the oldest kids are 6 and 5, which I have heard is a good age for it. And they do play and enjoy Uncle Aaron's DS. In a way I am being a little selfish because I want it. I have tried it too and had fun and was a little sore afterwards.
And once I am convinced I need to convince Nick... he is even less inclined to get it.. though I did say if we did he can get me the wii fit and I can have a smokin hot body!!!
Thanks!

C-Ya!
