Haha, I loled.
My Wii is connected to my TV 24/7
but then again so is my Sega Mega Drive (Genesis) so I probably am not a good representation.
Anyway, it's just silly for him to say that, the Wii has a higher attach rate than the PS3, and according to all those studies, has more play time (I think even more play time per console, but don't quote me on that)
