-I just picked up a new book edited by Ray Duncan ("Extending DOS").  As part

-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   %

Given that may people (myself included) have bought DOS many times; 2.0,
2.1, 3.0, 3.1, 3.2, 3.2, 4.01 in many cases for the same machine.  And given
that the Macintosh OS is given away free, and people who had pre 6.0.x
versions of the OS just copied the OS from their friends, IMHO I don't see
"sales" rates as a valid comparison.
