Joe88, I didn't even mencioned the motion control, witch is the last fotocopied "innovation" of sony.
Eyetoy was not the first camera too, but Dreameye, only launched in Japan. Blu-ray is just another optical-disc, first used in videogames in PC-engine. And what is Cell? A processor with graphic built in? That's creative!
I'm talking about everything. ALL this "so many great games and exclusives that no one else had" colud have been launched for any other mainstream in the marked, except if it was developed by sony itself. Then you see no one couldn't have been launched for Xbox, Gamecube or even Dreamcast.
In the other hand, sony's hype about ps2 made most of people think it was really the best machine in the market, when it was no better in power than Dreamcast. With 70% of market share, some of the great games lanched in the three major systems were all limited by ps2's power, limiting what could have been done in Gamecube and Xbox, much more powerful engines. That's the kind of thing we lost.
