>it was that Windows had already lost (largely because their competitors changed the game.) Competitors no longer compete only with Internet Explorer, they now offer an alternative to the entire Windows OS. Linux on the desktop (GNOME/KDE) didn't win per-se, but the browser did win, and Windows isn't a necessary choice for a browser-first system.

Is that reflected in sales figures?

They do acknowledge competition from Apple(OS X and iPad) and Google(Chromebook) and OS X has been offering a very big and popular alternative to 'the entire Windows OS' since inception.

How can you say Windows already lost while they are shipping on 85% of the PCs and laptops in the US and much higher worldwide?
