Discontinuation
In the Macworld Conference & Expo for 2006, the MacBook Pro was released. These MacBook Pros only came in 15.4 inch models, at first, with the Powerbook coming in more. These 12-inch, 17-inch, and 15-inch PowerBooks stayed in the Apple Stores, until they ran out. In 2006, the PowerBooks were soon being replaced by the MacBooks, as of the 17-inch PowerBook G4 was replaced with the MacBook Pro 17-inch, and the 12-inch PowerBook G4 remained available until May 16, 2006, when the MacBook was announced for the replacement for the iBook. The 15-year Powerbook line of computers finally ended.
