There exists a software company called Microsoft.  Perhaps you've heard of it.  It makes, among other things, two major pieces of software:  The operating system Windows, and the productivity suite Office.  Both Windows and Office are updated every few years, and instead of using some sort of intelligent auto-incrementing versioning system, Microsoft decided to go with whatever felt good at the moment:  3.1, XP, 2003, Vista, 7, etc.  For this, Microsoft is deservedly criticized.  However, being the nerd that I am, I'm baffled by the fact that people can't understand the difference between Microsoft, Windows, and Office.  I've heard many a computer-user say, "I think I have Microsoft 2007," or "I'm using Office Vista."  To set the record straight, here's the deal:  Either you're using

Windows [3.1, 95, 98, 2000, XP, Vista, 7]
... or ...
Office [95, 97, 2000, XP, 2003, 2007].

That's it.  I know the version numbers are hard to remember, but since both pieces of software are used by something like 90% of computer users on earth, let's all become nerds and try to remember these things.  Thank you, and have a nice day. #technology
