I won't add much new stuff, but in no particular order:
1.) N-Gage: I managed a Gamestop for 2 years during the launch of the N-Gage, and didn't sell a single system or game for it. Not one. In two years. Unless you count the free one we got at our manager's conference, which I promptly traded in for store credit when I got home. Um, ouch. Single worst console launch/system performance of all time.
2.) Virtual Boy: Red.... headaches... make it stop.
3.) 99% of anything related to the N64: I loved the N64, but Nintendo did just about everything wrong, and unfortunately at a time Sony seemed to do everything right. The few gems in the N64 collection pale in comparison to the squandered potential of the system. Cartridges over discs and completely shutting out third parties being two of the most glaringly obvious wrong decisions. (Though it did give us the ever glorious Aidyn Chronicles.)
4.) The SNES addon that became the Playstation: Probably a mistake on Nintendo's part, but who knows how gaming would have evolved if it did happen?
5.) RROD: Only thing that stood between MS and market domination this generation of systems. (Well, at least against the PS3.) Giant blunder, and the repairs after the fact aren't enough to overcome it entirely.
6.) Everything Sega did related to Dreamcast: Great system + terrible marketing = dead hardware manufacturer. Maybe for the best in the long run, since Sega can go back to focusing on games. (Wish they'd get back to being very good at that again. *cough*NewPanzerDragoongame*cough*)
Most of the others in the thread cover the majority of the other notables. Just shows that no console manufacturer is anywhere near flawless.
The dedication you show to any particular console or company is inversely proportional to the number of times you have gotten laid. If you get laid enough, even if you prefer a certain brand, you just don't give enough of a shit to argue about it on the internet.
