I'm not sure I understand the PS4/Xbox craze..... It's not like Sony used a magical "Sony System" to create their machine. They probably used MICROSOFT Computers to build the PS4. So did XboxOne. Both companies, I'm sure, use those same computers to run and maintain certain servers and protection agents. There's no winner in the war of anything. Except sales and hype. However, Sony did not make their dream machine using Mac systems ... sooo.... isn't Sony building their ultimate gaming Machine on the backs of Microsoft? Just a thought. I play and enjoy both systems and could care less about the battles. Xbox One is less powerful by a fraction. PS4 is specifically for gaming first whilst Xbox is entertainment overall. Halo probably saved the initial Xbox. It all doesn't matter.
