Sony like Atari, like nintendo, like sega and like the makers of the 3do consoles thought they had the gaming world by the ears and thought just as nintendo thought with the n64 that they could bully gamers into liking what they were doing and it's backfired and allowed MS to get in the game.
Sony has made blunder after blunder with the PS3 and continue to do so and they are too arrogant to admit it which is why they sit in third place in console sales.
Everything they did right with the PS1 and 2, they've managed to screw up with the PS3.
Sony tried to give us a machine that was a do all machine instead of giving us a game machine. Nobody needs USB ports and flash card readers in a gaming console. That's what PC's are for !
Why would you need to download photo's, video's and music to a gaming console ! It serves no purpose as it does nothing to enhance game play !
Atari blew it big time, Sega never recovered from the Sega Saturn fiasco, Nintendo let the N64 doom their fate because they thought they could keep the lucrative cart based business model that had made them millions during the NES and SNES days and after sitting on top of the gaming world with their NES and SNES consoles for about 10 years, they botched it by making the N64 cart based instead of using cd technology and Sony siezed an opportunity with the cd based PS1 and the rest is history.
The 3DO never gained any serious ground and faded early on !
