I suppose it depends on the country etc.
I have never seen an Apple II in real life. I suppose they were more common in the US, especially in schools?
Apple Macs also were quite uncommon here, but they did exist. They have become more common since, later PowerMacs (especially notebooks) and more so the newer Intel-base notebooks.
In the 80's I've mainly seen Commodore 64/128 (even used for business), Amstrad CPC (my school had some of those, less common in private households than Commodore), Atari ST, Amiga, IBM clones.
No Sinclair Spectrum here, but I think they quite common in the UK.
