Vast software library
Let's get the low-hanging fruit out of the way. One of the biggest assets of Windows 8 is its vast, deep collection of available software. (I'm talking about desktop apps, not those on the Windows Store.) Sure, Mac apps are slick and streamlined, and, yeah, Linux can cover your basic needs fairly well. But neither holds a candle to the cornucopia of programs available for The OS That Bill Gates Built. Chrome OS? Pffft. I dig the vision and experience, but sometimes life goes beyond the browser.
A big part of Windows 8's dominance in this category can be chalked up to its next triumph...
