I tell you, all piracy talk aside, I would pay money for the ability to run a new build of XBMC on my PS3, especially if I can get it to boot directly. I use my ps3 in lieu of my xbox as a media player, but it lacks in almost every category except Hi-def.
Waiting patiently for more info.
I'll assume that this wont be the only mod coming out. Clones and other alternatives will hit soon, some of which will probably be internal solutions so you dont even need to see a usb stick.
I'm stoked.
