Actually cars are numbered by the year. For example I have a 2006 Honda Accord. Not the best analogy.
Apple laptops would be the better example. People just say I have a macbook or I have a macair, but not which one. Even other makers just call it a "Dell Latitude" or something in general and you normally have to look a little harder to find the model number of latitude it is.
Uh-huh. And what year did the 2006 Accord come out? 2005.
