A CDE Definition
Apple's first family of laptop computers, introduced in 1991 with a monochrome screen. The first portable to feature a wrist rest on the keyboard, PowerBooks were very popular and lasted until the MacBook line in 2006. A color Power Book came out in 1993. Although not terribly popular, there was an Apple portable prior to the PowerBook (see Macintosh Portable).
Like the Macintosh desktop evolution, the first PowerBooks used Motorola 68K CPUs and subsequently changed to PowerPC chips in 1995. The last PowerBook was the PowerBook G4. See MacBook, iBook and Macintosh.
