Yup
No matter how pointless they seem to the PC enthusiast crowd, plug and play boxes will never go away, at least not for a LONG time.
I play a lot of games and the idea of spending 800+ dollars and doing all the work to set up a PC is something I have no interest in doing. I doubt the mainstream consumer is more inclined to do that.
Consoles will continue to make sense as long as people want to play AAA games in the easiest and cheapest way possible.
