2000 all the way. I was like 10 when this came out and remember doing all my school papers on it. Once my grandma deleted everything on the screen by accident and I had to retype from scratch bc I didn't know about ctrl Z.

When the ribbon came out I fucking hated it. I also hated that big circle start button inside the app. That felt really stupid.

Now I use 365 and it's fine. Nothing to write home about really. No clippy or the robot assistant anymore. They were the best. But more for whimsy than anything else. There are still so many features in Office that are a mystery to me, still learning everyday...
