I think what Coded-Dude means is that the 360 would cost more if you were to match the PS3 feature for feature. The 360 would need a $200 HD-DVD drive and a $100 wireless adapter.
True, but as a gaming machine (which is the grounds on which I'm basing the comparison) it lacks only the Wi-Fi adapter. Blu-ray/HD-DVD is an entirely different discussion.
And honestly, if I had been buying purely for software support, and the consoles were the same price, the 360 would STILL be the better buy.
