That's true, during the time I had a 486 SX 33 with 4 MB and 200 MB HDD. Windows 3.1 ran fine, I tried OS/2 Warp and it was unbearably slow. Never tested Windows 95 on that computer but of course NT was completely out-of-reach. On the other hand "NT" was unusable for anything fun until XP.

Still, there's a point to make about bloat but the comparison seems to be between Apples and Oranges
