I just read the series of correspondence considering the Xerox machine and
the usage of the term "Xerox" to refer to photocopying. Now the problem I
have does not have to do with the term but with the use of advertising by
providing a free product. Adobe acrobat and its free reader for pdf files
was the first thing that came to mind. Is it really cost effective for Adobe
to provide a free pdf reader when they could possibly sell it on the open
market. I know they sell other products related to pdf files, but is the
advertising of the free reader really encouraging people to take advantage of
their other products or is it causing people to abuse the reader and its
benefits. Seon
