The PC is definitely not going extinct. What was going extinct was the Windows interface/way of doing things. That being said, any good software developer knows that design and dev are not mutually exclusive. A product can look absolutely spectacular, but fall apart due to bugs and other issues. Unless Windows 8 manages to completely eliminate things like the BSOD and frequent crashes, a new interface won't change a whole lot.
