Have you taken a college course
not since the advent of PC, but I know even some grade schools seems to require Microsoft junk and tests via WEB Pages. That only indicates to me the quality of our (US) education system, seems 'real' teaching went out of style in the 80s.
had to deal in a "business-to-business" interaction at all in the past 15 years?
Everyday, what I want to say is either in the email body or in a text file or rarely a Libreoffice doc. If I have to deal with Microsoft formatted files they can deal with file formats I prefer.
