The lack of preemptive multitasking didn't mean that people didn't want to run a Unix-like OS at home, if that's what you mean. MSDOS was horrible, and regardless of the capabilities of your machine one would probably rather use something else.

I had Amigas with 68000s, and one with a 68030. AmigaOS didn't have any special capabilities on a 68030 that it didn't have running on a 68000. AmigaOS was a Unix-like IS with full preemptive multitasking that could operate in 256k of address space, on a 68000.
