I liked Windows 3.1 so much that I used it as my main OS until 2003. The combination of Windows 3.1 and MS Office 4.0 was great. I don't think there's been a significant improvement in Word or Excel since then.
If pressed, I'd say that the greatest changes for general office use in the last twenty years (for me) involve multiple monitor support and touchscreens.
