Seeing as Metro/Win8 is MS last desperate push to enter the market for tablets that in the near future will replace the market where they currently hold almost all their monopolies (the desktop), that's a very accurate description of what will most likely happen.

And seeing as Windows is not and never was an OS for power users, they will lose the remaining desktop niche - which will be populated by exactly those power users - as well once the tablet will be our primary multimedia communication device.
