iBook
(1) Apple's previous e-book app for iOS, which was renamed Apple Books. See e-book.
(2) An earlier family of laptop computers from Apple. Soon after the first iMac, the iBook debuted in 1999 with a 300 MHz G3 processor and a built-in wireless antenna. At the same time, Apple also introduced its Wi-Fi family of products under the Airport brand name.
iBooks and PowerBooks
The iBooks were consumer-based laptops aimed at students and beginners, while the PowerBooks were Apple's higher-end laptops. The iBook G4 was the last iBook model, and both the PowerBook and iBook lines were superseded by Intel-based MacBooks in 2006 and 2007, respectively (see MacBook). See PowerBook, iMac and AirPort.
The Original iBook
Although subsequent iBooks were more streamlined, the first iBook was very popular. It offered a somewhat playful look in the midst of all the look-alike products of that time. (Image courtesy of Apple Inc.)
