I know this is an older thread, but I am answering your question. I run linux only on my computer. Windows has become a trojan. So I moved to linux and have been using it solid for several weeks now. No problems. So no, most linux users do not dual boot. And if there is a windows only game that will not run on linux ( or Wine ) because the devs are just lazy, then we linux users simply move on to other linux supported games. And since Microsoft announced no more windows.. this means everyone will be switching to linux over the next 5 years. So linux versions is definately needed and is the future, until some other better OS comes along. My Linux looks and feels like Windows. But I don't have the spyware / trojan known as windows to worry about. Microsoft uses windows to use / take all your person info about you and sells it. It's in their windows Terms of Service. Which is why a LOT of people are switching to Linux now.
On another note.. Microsoft now uses linux as their servers. They announced it in one of their video conferences. So now you can see why Linux is the next biggest OS for the future instead of Windows. Which thanks to MS, its dying.
