It looks like Microsoft has written a little article comparing the specs of the Xbox 360 against the Sony Playstation 3.  Guess who came out on top?  Take all this with a grain of salt…
We decided to put this Microsoft-provided information up undigested. Thus, enclosed is a Microsoft-made comparitive analysis. We have not altered, added, or tinkered with the data. We have not interpreted the specs. We have cut and pasted this information from the email into our site and formatted it. Make of it what you will, but be clear we know Microsoft has clearly slanted this info, and we’re not endorsing it, just printing their version. There is a difference.
