I love that Don Norman gave the foreword for the UNIX-Haters Handbook (1994) and he cites his own paper from 1981:
Norman, D. A. The Trouble with Unix: The User Interface is Horrid. Datamation, 27 (12) 1981, November. pp. 139-150. Reprinted in Pylyshyn, Z. W., & Bannon, L. J., eds. Perspectives on the Computer Revolution, 2nd revised edition, Hillsdale, NJ, Ablex, 1989.
