What I miss the most is the extension system. Where installing something (driver, new feature, etc) on the OS is as simple as dropping a file in a folder. And uninstalling it deleting this file. And you know there is nothing left after you removed the extension.

What I don't miss is when the extensions conflict, crashing the machine on boot.

I also don't miss the process of removing each extension one by one, rebooting each time to find the culprit.

That's still way better than trying to figure out which driver is causing a BSOD on windows today.

Let's keep in mind this was a pre-protected memory OS.
