I don't think PCs are dying. I think computing consumption is increasing so desktop productivity looks like it is declining.
I think when a dock for tablets or phone finally happens for consumers, they'll just get it. Desktop mode is not intended for using your fat fingers on a touch screen. "Metro" mode is for that. Windows 8 is all about for when you get off the bus in consumption tablet mode and dock into your desk and your dual monitor with keyboard and mouse lights up and you go into productivity mode.
