What's wrong with you in the sense of why don't you own a 3DS yet? There are a lot of people who haven't taken the plunge yet with the system and up until now I could see some reasons why. However, this holiday is going to be mainly about Battlefield 3, MW3, Zelda and the 3DS games. Mario Kart 7 and Super Mario 3D Land are going to be heavy hitters for the 3DS and will probably rack up the sales and system sales for the system to become an honest to goodness hit.
If you haven't purchased a 3DS yet, what holding you back?
