Malachi - But how many PS2's get thrown away when they are replaced? I doubt Sony just takes, or took, a $200-300 device and threw in it the trash.
That's why there are products called "refurbished" units. Sony took the old, broken systems and fixed them up, and re-sold them to stores, most likely. All companies do this. GameStop sells quite a few refurbs from the manufacturer, as it's an easy way to get 30% off the regular price of a system.
Back from the dead, I'm afraid.
