The main reason I bought my PS3 in Dec 2006 was because I had good experiences with my PS1 and PS2 console. I never had problems with either system, and still have my original PS2 from 2002. WIth the first PS3s being backwards compatiable, I saved up the money and bought it the first time I saw it. Basically, I had faith in the brand. And like others here, I wasn't excited by any of the games, so I didn't preorder one. Besides, in 2005-2007, I was still playing Battlefront 2 online almost exclusively. I continued to play that game the first couple of months on my PS3.
Once MotorStorm was reelased in Mmarch 2007, I played that game online non-stop for months. I'm not much for exclusive games either (little personal interest in MGS, Gran Turismo, or GTA), but new franchises like UNCHARTED and HEAVELY SWORD are great games that make me happy I got the 60 GB PS3 early.
