Ummmm.....  Protected-mode Windows WAS delayed until the 80386.   (Or
am I missing the joke?)  Windows 286 (aka 2.10) was real mode.
Windows 386 (also having version number 2.10) had a 386 protected mode
kernel that used the virtual 8086 mode to separate tasks.

AFAIK, the first windows with a 286 protected mode was Windows 3.0
with its "standard mode".  A lot of Windows 286 apps wouldn't run in
standard mode.
