I grew up with DOS.
286 in the house, … like literally in the center of the house, but we did have like a gui program called ezmenu. Still had to launch a lot of programs/games from directories though

Don’t forget desqview. Best multitasking ever. One of my PCs could run 3 nodes of my BBS and a working session.

Or GEOS. An os-thingie with mouse and shit 😁

Also don’t forget OS/2. Which really was great compared to the first windows…
