Hardware multitasking and context switch on interrupt as well.
Admittedly I didn't live through that time period, but reading about them, they are quite interesting. It seems that the main reason they were considered "brain-dead" was because you couldn't run 8086 native and 286 native software at the same time, and backwards compatibility and interoperability started becoming something people considered very important.
Interesting enough that I went and bought a static core 286 (the 25 MHz Harris one) to play with. Since it's a static core I can run it at whatever frequency I want, even if that is only a few hertz.

Things to keep me sane during the pandemic isolation :)
