The thing is that unix names generally tell you what the function is;

grep = general regular expresssion parser
cat = concatenate
vi = (the odd one our here) The name comes from the shortest unambiguous abbreviation for the command visual in ex

Office Plus & Office Enterprise really do not offer any clue to the differences by reading the name. Microsoft is missing the naming plot, wtf is "Windows Defender" I prefer "Microsoft Anti-Spyware" atleast now I know what it is defending against.
