What do you know today that you didn't know yesterday?

my dad learned wordstar in the early 1980s. till he retired he refuse to use anything else because the hurdle of change was perceived to be much higher than the convenience of a more user friendly product. At the time when there were not yet any on-line catalogue of professional papers in his field, he would actually copy the abstract of all the new papers into a giant word star document so as to be able to search for key terms later.
