Well, I for one find virtual desktops to help in a couple of ways. For example, there are some tasks where I need multiple programs open full-screen simultaneously, and it's easier for me to just Win-Tab to the desktop with the one I need at any given moment, rather than trying to pick the program out from the taskbar. I've also found them useful for categorizing tasks; such as having one desktop for my design apps, another for productivity, another for various random tasks, things like that. It's one of those features that you don't really think about until you start using it and learning how they can fit your own workflow, and then you'll end up wondering how you ever got along without them! And really, the fact that it took Microsoft until 2015 to add them to Windows is pretty surprising. Amiga users had them since 1985, *nix users since 1990, BeOS included them in 1995, OS/2 Warp 4 had them in 1996 (Windows NT never did), and Mac OS introduced them with 10.5 in 2007. Windows was really the last holdout. Millions of people using other operating systems (or third-party programs) have had virtual desktops for literally decades.
