I have to recommend Linux Mint. I’ve been using Linux Mint (Cinnamon) for over seven years now as my only operating system (and no dual booting) without any major issues or any desire to “distro hop.” Cinnamon has also gotten a lot more stable during that time too. I have almost no crashes anymore.
Windows XP Pro was the last Windows that you could install on as many of your machines as you wanted without contacting M$. When I found that out, I knew that XP would be my last Windows and that I would inevitably switch to Linux. When XP became totally obsolete, I permanently switched over to Linux Mint. I’ve never gone back to Windows and I have zero reason to ever do so. I promote Linux whenever I can.
