I'm tempted to take my free upgrade from Win 7 to 10 but I have some worries of how well Unity and Visual Studio 2013 will run on it. If my PC was strictly for my personal use, I'd probably go for the upgrade but it's the only PC I have and upgrading to 10, encountering some severe issues, and not being able to go back is a legitimate concern of mine. On top of that, I absolutely despise Windows 8 so not too much confidence in MS's next offering Anyone here have any experience with Windows 10 they can share? Or thoughts in general? Are you guys going to upgrade your development machines?
