Oh man, the Atari 5200. I'd almost forgotten. We didn't have a 2600 but my folks got duped into the 5200 being 'the next big thing'. I guess I should be grateful, without that failure my folks wouldn't of had a reason to buy the Commodore 64 later on which not only had games but also could be used for a lot more.
Also, when talking about E.T. and the landfill you are obliged to link to the music video made by an indie band about the fiasco[1].
