Can I imagine? Yeah, I lived it. Even Internet browsers used to be text only. My first modem was <1 kbit/s. (For contrast, the last dial-up modem speeds were 56,000 kbit/s, and today speeds are often 1,000,000 kbit/s or more.)

The mouse came before graphical OSes for me, since games used it but they were executed from the command line MS-DOS. Of course DOS was also capable of using a mouse. I didn’t really use an OS GUI until Windows 3.1, which was mostly a novelty at first. That came out in the early '90s. I didn’t have any exposure to Macs until System 7 in the mid-'90s.

My daily driver these days is a MacBook Pro. We’ve come a long way!
