Im not entirely too sure why people are bytching as much as they are about Metro. You can literally get to the old school desktop in less than 5 sec after launching the OS and never see Metro again if you don't want to. However, Metro itself has so much going for it its not even funny. Live tiles, fluid animations, great UI interface, and an overall fantastic experience. But even if you consider yourself an old curmudgeon that hates the idea of changing from the old desktop interface, Windows 8 has that. Or better still, you can stay with Windows 7.
People are such fakkits it makes me sick. Apple makes any change and people praise it to no end regardless or how pointless or retarded it is. Hell OSX lion was literally a downgrade from Snow Leopard and people somehow refuse to say so. I personally think Snow Leopard is the GOAT Mac OSX and still run with that on my Macbook. In general, Windows 8 has literally passed every other OS on the market right now in terms of interface, smoothness, and overall usefulness.
People just love to bytch, especially whenever M$ is involved. Its so disgusting...
