Yeah, I'm not a big fan of the "technically you're getting $900 worth of stuff in the PS3 so $600 is a steal" thinking.
To me, $600 is way more than I ever plan to spend on a console. It's like my grandfather who buys stuff at the grocery store that he doesn't really want because he has a coupon. Yes, technically he's saving money, but only if he wanted the thing to begin with.
I don't want a Blu-Ray player. I don't want any of the PS3 games available now or in the near future. I don't want a media center for my entertainment center. I just want fun games.
That's why I'm buying the Wii. For $250, it's within the price I'm willing to pay and the controller is really fun to use (I got to try one at the local EB Games).
