I hope Windows 8 fails simply so that MS is forced to admit they made a mistake, and then "relaunches" Windows with the desktop unfuglified and with full original functionality restored ("Due to popular demand, we are bringing back the original desktop functionality...nudge nudge, wink wink...).
There is no reason to castrate the desktop for the sake of Metro. Metro can co-exists alongside a full functional desktop that should be a refinement/evolution of what we had in Windows 7, not some Frankenstein monster that most desktop users seem to hate.
And this horse isn't really dead since this is a big issue and will continue to be a problem for MS until they fix it. Those that like to pretend nothing is wrong are free to ignore threads with titles that clearly show what it is about.
