I voted other. I’m not using Windows 7, I won’t know if Windows 9 is an improvement until I’ve installed and used it, and I have no interest in ever learning Linux. I’d just stick with Windows 8 if I decided no to upgrade to 9. That said, I’ve never had any problems with Windows 8 or 8.1, and have never quite understood all the complaints about it. There are very easy fixes to everything I’ve seen complaints about. Anyway, I like to keep current with software, maybe I’m even a little excessive about it, so I’ll most likely upgrade to Windows 9.
