I don't actually own a console so I don't know this - can you plug a keyboard into a console and use it?
As for the shift from PC to console gaming, I suppose from a developer's POV it's much simpler to program a game for a fixed platform as opposed to trying to make sure it works for all PC configurations. But I still think there are games that can only be played on a PC, and don't translate well to consoles.
