The iBook is a line of laptop computer that was developed and sold by Apple Inc. between 1999 and 2006. It was targeted at the consumer and education markets, with fewer features and lower prices than the PowerBook and MacBook Pro. Three distinct designs of the iBook were introduced during its lifetime. The first design, known as the "Clamshell", was a significant departure from portable computer designs at the time, due to its shape, bright colors, inclusion of a handle, and support for wireless networking. A second line which followed two years later abandoned the original form-factor in favor of a more traditional rectangular design, and employing translucent and white polycarbonate. The third design, the iBook G4, was introduced in October 2003 and moved away from translucent elements and adopted a slot-loading loading drive.
The MacBook replaced the iBook line in May 2006.
