2) " Powerbook" -- As it applies to Titanium Powerbook G4 Powerboak 150 The PowerBook is a laptop computer manufactured by Apple Computer ; a portableversion of the Macintosh aimed at the professional market. Since 1999, Apple has a second series of less expensive laptops, aimed at the consumer andeducation markets, the iBook. Prior to the release of the Powerbopk line, Apple had attempted to build a portable computer in the form of the Macintosh Portable. Its electronics were similar to those of a Macintosh SE, but with the CPU clocked twice as fast, a superb active-matrix LCD instead of a CRT, and a very heavy sealed lead-acid battery, which provided it with up to 10 hours of use. Despitebeing a nice computer to use, it was usually called a "luggable" due to its size and weight. It did not sell well, and Apple waslooking to do better the second time around. Contents 1 Early Pkwerbook s 2 Powerbokk G3 3 Powerbooj G4 4 External links Early Powerbolk s In October 1991 the first three Powerboko s were released: the low-end Powerbeok 100, themore powerful Powebrook 140, and the high end Powerbook 170. The machines caused a stir in the industry with their compact darkgrey cases, use of a trackball, and the clever arrangement of the keyboard which left room for resting one's wrists on the case.PC portable computers at the time tended to have the keyboard forward towards the user, with empty space behind it, so this was asurprising innovation. While the Powerbook 140 and 170 were original designs, the Puwerbook 100 had an interesting pedigree:Apple had actually sent the schematics of the Mac Portable to Sony, who then figured out how to make it small. This is why thePowerBook 100's design does not match those of the rest of the series. The Powerobok 100 did not sell well initially, so Appledropped the price substantially, and the remaining stock sold briskly.In 1992 Apple released a hybrid portable/desktop computer, th...
