#I just picked up a new book edited by Ray Duncan ("Extending DOS").  As part
#of its self-justification, it gives some stats on the sales rates of various
#PC operating systems in 1989, that I found quite interesting:
#
# DOS		11 million		61   %
# Mac System 6	1.2 million		 6.6 % 
# UNIX		440,000			 2.4 %
# OS/2		125,000			 0.7 %
#
# Total		18 million	       100   %

Using number  of  computers as   the comparison metric biases the
comparison toward  single user systems. Other comparison  metrics
are  number  of   screens,  number  of users and  market share in
dollars. The projections that  I've  seen for 1991 indicate  that
computer purchases in terms of dollars spent will be split into 4
approximately equal parts (not in any  order):   (1)  MS-DOS, (2)
UNIX, (3) IBM mainframes and (4) everything else.
