No. I have all my consoles going back to the Atari 2600 my father brought home.
First of all, I always wait until a console has some interesting games before I buy one. Second, I can't imagine getting rid of something I paid full price for and getting on a fraction of that back, then having to re-purchase a new one if and when more games arrive. The wasted money would make me feel sick.
Really, why even buy something if you have no faith in it?
