... how many applications or even operating systems are you still using of a similar age outside the Office suite?
Obvious 'tard-bait, but as it's Friday:
I am now logged into Debian, first release 1993, based on Unix initial release 1974. And editing a file in LIbreOffice, based on OpenOffice, based on StarOffice, released 1985. Yesterday I interviewd for a Solaris job. First release 1982 (SunOS). And I just used "vi" to edit a file. First relased 1976.
