All hardware is the same because they can run opengl/directx? Thats some outstanding evidence there. Get a clue.
Not that I want to get involved with the bitch slapping here. But he is right. Xbox can do what it does because it only has to do one thing. And it is optimized very well. PC"s have to be able to do a million different things. With a million differen't combinations of hardware. Thats the wonderfull thing about PC's. But really they are pretty inefficiant because of it. Thats why a mac is faster at lower clock speeds because it is (for the most part) a closed system. It can be optimized better. But look in the PC sore shelves. Everywhere you look there is PC stuff. Millions of products. Look for the Mac section. Theres like one bookcase.
