I don't see that coming in the foreseeable future, unless they make a Linux desktop that is as user-friendly as Windows.
What if they keep trending towards making Windows as user friendly as Linux?

As in, if Microsoft keeps taking resources out of the Windows division in favor of Azure, we might end up in a place where the Linux desktop wins not through becoming better, but by Windows becoming worse.
There's no more VP of Windows. It's pretty clear MSFT is making a hard cloud push. Seriously - they gave out Windows for free for three years and NOW you think it's not a priority?
