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.
By the way, I wonder what kind of homebrew games and emulators I can get for the ps3. I know I can program the 360 with the toolkits I have here at work. With my Dreamcast, I could emulate anything.
