Here is an interesting article from early 1988 (probably written in min 1987) that compares and contrasts GUIs of the day. Interesting that they do not mention OS/2 by name, by this point it would have been available, given I used it in Jan 1987 when I was working at IBM. Also the XEROX interface was not yet dead as the author makes it seem. If anyone used Page Maker on a 1987/88 Xerox machine and compared that with "Windows OS/2" machine trying to run the Page Maker on a PS/2 80 you'd probably agree.
Basically I am unsure what planet the author was from, but you can decide for yourself. Talks a little about HP's GUI product, Sun/AT&T, Apple Finder, etc. Mentions NeXT is coming, Commodore is dead, ... opinionated. http://vintagecomputer.net/cisc367/PC-Letter_19880118.pdf Bill
