I bought a Wii in 09 after playing it at the friends house. I thought it was fun, and good that it included some movement in some of the games.
Then, 3 days later was the 'project natal' demo and I was like FFUUUUUUU.
But I was happy with my Wii played through, SMBB and Zelda TP. Got more games, bought even more games. Showed it to friend, they bought Wii's.
Then I got an HD TV and it didn't cut it anymore. I was sad - I need a HD system - I was more attracted to the Xbox because: my friends weren't too excited about their PS3's, had played Xbox's with my nephews and it was fun, the 'S' came out so I wouldn't worry about RROD, and liked the community outreach of the companies Microsoft over Sony.
