Is much better on the 360 than on the PC by the way

PC loading times are horrible, 3 or 4 times that of the 360 and not that much prettier. In the demo at least...
The replacement under warranty with a 65nm thing was a bit of a joke really. However I think it's safe to assume that MS will have stopped production of the 90nm 360 chips already, so future motherboards will be the 65nm versions. Return your console in 6 months and you'll get a 65nm version back.
I'm hoping that when / if (and i'm guessing it'll be a matter of when) my newer 360 goes tits up (bought easter 2007, manufactured summer 2006) it'll get replaced with one of those HDMI premiums, hopefully with the 65nm chips and a quieter dvd drive
I appreciate what you mean about the noise though, it makes a racket! Luckily it's rarely an issue for me as the TV (mostly) drowns it out.
