Chiming in with the others - I did. I didn't do a lot with it, but I did. Didn't even know what an assembler was - I just though everyone did it by hand.
I'd read some code that showed JMP $5000 and LDY 32 and figured people just knew that JMP was a particular byte, and LDY was a different one, and you just did it. While it did seem cumbersome, I didn't have much else to compare it to.
I wrote some small screen animation utilities (ASCII screencast recorders, essentially) and later some C128 'enhanced graphic mode' stuff, moving a pointer with a mouse. I think by that point I'd learned the C128 had a small assembler tool built in, so that made things easier.
