Have used the ps3 on a 47" Plasma. NICE a decent web browser with lfash functionality. Youtube works well. The WII browser was nice and it was initally free. NOW Nintendo charges $5 for the internet chanel. so $5 per Wii user if they want to hit the net. Smart way to make monet on the millions of Wii's out there.
Unbutu Link on PS3, or any linux distro on the PS3 is a mixed bag. Getting hdtv display working was a nag, never got it to full hd.
