# 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.
