Exactly. Free vs. $8k (in 1990 dollars) for a NeXT computer was a pretty easy choice for most people.
to be fair, nobody in 1990 decided between NeXT and Linux, because (A) Linux didn’t exist yet and (B) they were / would have been completely different markets and totally different capabilities.
"Free", until mid 90s I guess most people bought Linux distros on CDs, later DVD (no downloads). For me the big, big plus on Linux (vs. Dos / Windows), had been all the free compilers.
