Addressing and cost
Up to the 486, x86 addresses consisted of a 16bit pointer within a 64K block and a 4 or 8 bit block selector. Memory over 640K was addressible only via a kludge because the BIOS used some addresses in that range - meaning you could bring the system to a stop by POKing in the wrong place.

Yes a Sun 3 cost mor e- but not $75K. My 3/160 cost me
$18K Cdn - you could spend $75 - but that got you bigger disks, dual monitors, and more memory than my million dollar vax had at the time.

The Mac was cheaper then the PC at the time too.

OpenLook kinda sucked - what made motif a winner was Adobe's insistence on licensing fees for PostScript while MIT made X free. Sun's NeW's was great, but needed a postscript display; X was ugly and slow, but free....
