I played a PS3 at BestBuy today, Below are my observations.
1. First Impression was, Damn this thing is huge, but overall pretty cool looking.
2. The controller, Felt like a PS2 controller with want to be 360 triggers. NO RUMBLE
3. The PS3 interface is pretty slick nothing exciting though, I still prefer the 360's Dashboard.
4. I was able to play 3 games, NBA 07, Motostorm and Genji, The load times in the games were crazy long.
5. NBA 07, Graphics sucked, all the players looked like they were modeled from melting plastic. Gameplay was ok, But very unimpressed compared to NBA 2k7.
6. Motostorm, Graphics were pretty sharp, but textures were not NEx gen. Physics sucked and there is no sense of speed.
7. Genji, Graphics were pretty slick but gamplay was lame as hell. Like a lame version of Dead rising, push 1 button and kill.
Overall, I was very unimpressed, I will stick to my 360 untill PS3 improves it's lineup and proves itself.
