We ran into a few vertical apps that required Z80--and I think one of
the better word processors (maybe a late Spellbinder?) required a
Z80. BASIC dialects were different enough back then (and today) that
an application written with a specific Z80 BASIC in mind would get
you into trouble with an 8085.
It wasn't enough to make us consider developing a Z80 card, since we
were marketing our own OS and applications anyway. But I'm certain
that the lack of a Z80 cost a few sales.
