The Wii is just cool - I have a lot of friends asking me if I can get them a discount on it and I have to explain to them that it's not a Microsoft product.  But it clearly appeals to a whole new group of people - these are generally folks that have never talked to me about getting Microsoft products. 

 

But there are risks... (in addition to that you might even get some exercise ).

 

While I have almost no interest in getting a PS3, I really do think I might enjoy a Wii.  And I'm not alone. [update: fixed link]
