I never had the chance to use ME, instead upgrading from 98 to XP Professional last year.
Windows 3.1(1) is downright strange. Although the first computer I used had windows 3.11 - and thus that was the environment I first became accustomed to - in retrospect the program manager is very awkward.
I vaguely remember Windows 3.1 came with a tutorial on how to use the mouse. When I was five or six I thought it was a game and would do it over and over...
The only plus about Windows 3.1 was the WEP, which had a few simple yet addicting games. Chip's Challenge, Rodent's Revenge, JezzBall... the school that I spent 7th grade in recieved a windows 3.1 computer as a donation and the entire school of 15-or-so boys became a slave to the WEP... Even in the 21st century, they stood up as crude but timeless.
