Thanks Bill for the link. I'm trying to get either one of these systems in a budget for a home theater system as a media extender to my home server. The PS3 takes away the need to buy a blu-ray but the 360 seems to work as a more complete media extender. However, I can easily change out the HDD on the PS3 for extra homebrew software.
I haven't played with it, but there's a "Media Server" option under both Music and Video. I assume if you have a media server, you can detect it with the PS3 and stream whatever's on there...
OK, here's what you need:

You can run Linux on the PS3, so your emulation capabilities will be pretty extensive.
