Well, I just got my Xbox a week ago, and obviously its a newer model. The disk drive is the noisest damn thing i have ever heard, so i ripped my games to the harddrive and its virtually silent
I can't see a single difference between ps3 and xbox hd graphics, but then again, i've not played any exclusives.
Xbox Live is also alot easier to use than PSN, you can just add a person to your party, and talk away to them while in a completely different game
Concerning the RROD, it's never even slightly warm...
What i will say is, Microsoft really rip you off, no rechargable battery packs included, as well as no wireless included, so in that aspect its better.
I think the the reason we have so many Xbox vs Ps3 Debates here is simply because... its a gaming forum...
EDIT : seems the topic has changed, sorry
