I'm pretty sure it was more like a 130 dollar hit on the 360.
And even then, I was watching something on G4 and I saw that they've made little to no profit off the original xbox, the console market just isn't a great place right now. HD gaming is expensive, and IMO all the big money is going to the HDTV companies who are really profiting from these console being released. I wonder how many people have bought a big HDTV just because of thier 360 or PS3, I'd bet a LOT.
