Why are you still using Windows 7 ?

This isn't a post to insult or complain about Windows 7 users that haven't upgraded to Windows 8, I'm just curious, what is it that keeps you on Windows 7 ?

I personally hardly ever use Modern apps, staying on the desktop most of the time. But to me, Windows 8 is still far better than 7. Faster start-up times, new task manager, the Start Screen...those and many other things just make Windows 8 a joy to use for me. I honestly don't think I could go back to Windows 7, but I am curious as to why users are staying on it.

Like I said, I'm not complaining or insulting here, I just want a friendly discussion.
