Well, I could try to wait a little with Debian 9 as I did with Windows 7. That thing of no software updates is very weird. Windows 7 is many years old yet I can still use the latest version of Firefox. Isn't there a way to update user programs without updating the operating system itself. I read there was something called backports, but the warning about instability just terrifies me; I know more or less how to fix Windows, but not Debian.
