I can second this! For me it meant that I could finish my game of modded fallout new vegas, and connect to my work's microsoft vpn nonsense (IT support didn't fancy trying it on Mint but that's another story!)
I now have a personal OS that I like, and a windows partition for those few things that I can't be bothered to troubleshoot.
So far the list is just those things and the Unity Engine as Visual Studio debugs better than code in my experience. :)
Having the option to flick back is great :) In the XP days, I loved the WUBI(?) tool that let you install ubuntu dual boot as an exe, but I think that's not a thing these days., :)
