Yep, this study would have to divide things up by age. As a fellow member of the Oregon Trail generation, all my early computers were also Apple ][ and b&w macs. But then eventually by young adulthood it all turned into PCs.

I enjoyed a stint with Solaris in college (that’s SUN Solaris thankyouverymuch) which I consider my true intro to Linux/posix/whatever-ix.

I started on a Pr1me 550 type II learning BASIC myself. Apple ][s came out about 4 years later. Then I used them. Windows SA now.

My youth was at least partly misspent hacking z80 assembler on an Amstrad CPC664. Not as many regrets as one might assume. I miss when (8-bit) assembler was simple enough to hand-code without playing "surf the reference manual".

I learned basic on an old trash 80 from radio shack in the late 70's. I really miss mucking around with it.

Edit: Now I use Linux.
