Of course...
the 800 lb gorilla here that neither the article nor the commentators have the balls to acknowledge is Apple and its resurgent Mac platform, with OS X the absolute, undisputed, best PC operating system available. More people are lining up to buy Macs than ever, Apple remains one of the few _profitable_ PC manufacturers, and IT (at least outside of the US) is beginning to embrace OS X with increasing earnestness.
MS may try to copy more and more of OS X (Win 7 certainly shows they're trying very hard indeed) but there's really no hope for them ever to come close.
Bye-bye, MS, keep Balmer around for ever!
