Are we really saying that a major point of the success of the Wii and PS2 was their physical size? Yeah, if you reach the size of a mid-tower that would probably have people a bit put off, but the 360 at least (haven't spent enough time around the PS3) isn't large enough to bother. Power draw? Does anyone, even techies, ever really look at the power draw? Unless it pops the breaker when you plug it in, no one cares. You want to say powerful (for the timeframe) = high heat/ lower reliability = expensive -> fair enough. Physical size though, really?
