   The world is full of examples of terminology abuse.  Just  
yesterday I was told that someone had "gotten a satellite", referring  
to a satellite TV system.  And if I had a nickel for every time I've  
heard people, even knowledgeable people, incorrectly use the term  
"broadband" to mean "high-speed Internet connection" (when most such  
connections are, in fact, baseband)..

   It's a huge pet peeve of mine, but I try not to stab people too  
often.
