MacBook Pro
The first MacBook Pro was the 15" model, but a 17" model was released later that year. New models were released in late 2006, late 2007, early 2008, late 2008, and early 2009. In June 2009, a 13" model was added and the other sizes were also updated. The next updates happened in April 2010 and February 2011. Another update was released in June 2012, in which a new 15" model was introduced with a much higher display resolution (dubbed the Retina Display, meaning that it can display more pixels, creating a smoother image). However, Apple stopped making the 17" model.
