In October 1991 Apple released the first three PowerBooks: the low-end PowerBook 100, the more powerful PowerBook 140, and the high end PowerBook 170, the only one with an active matrix display.

Hence the PowerBook 100's design does not match those of the rest of the series, as it was actually designed after the 140 & 170 and further benefited from improvements learned during their development.

The original PowerBook 100, 140, and 170 were replaced by the 145 ( updated to the 145B in 1993 ), 160, and 180 in 1992.

In contrast to the high end of the 100-series line with which the Duos shared the same processors, the PowerBook 170 and 180 with their crisp active matrix displays were both already in great demand over the lower powered models with passive matrix displays.

The PowerBook and iBook lines were discontinued and replaced by the MacBook Pro and MacBook families respectively by 2006.

For several years, new PowerBook and PowerBook Duo computers were introduced which featured incremental improvements, including color screens, but by mid-decade, most other companies had copied the majority of the PowerBook's features, and Apple was unable to regain their lead.

The PowerBook 1400 and 3400 were in fact the first PowerBooks ever to include an internal CD drive, and were introduced in a time when laptops rarely had one.

These drives were also options on the 15-inch PowerBook.

In 2000, Apple's Power Mac G4 and PowerBook G4 were the first mass produced personal computers featuring the 1000BASE-T connection.

Three boxes of this strategy were already in place: The newly introduced iMac was the consumer desktop, the Blue and White G3 filled the professional desktop box, and the PowerBook line served as the professional portable line.

Such designations were applied to Apple Macintosh computers such as the PowerBook G3, the multicolored iMacs, iBooks and several desktops, including both the Beige and Blue and White Power Macintosh G3s.

* Apple Macintosh notebooks: Function keys were not standard on Apple notebook hardware until the introduction of the PowerBook 5300 and the PowerBook 190.

Several popular unauthorized workarounds were devised, including to use the power supply from the PowerBook 100 Series which provides a higher output.

Likewise, machines such as beige Power Mac G3s and " Wall Street " PowerBook G3s that were dropped by Panther ( the preceding release of Mac OS X ) can also be made to run both Panther and Tiger in this way.

The PowerBook G4 is a series of notebook computers that were manufactured, marketed, and sold by Apple, Inc. ( then Apple Computer, Inc ) between 2001 and 2006 as part of its PowerBook line.

Between 2001 and 2003, Apple produced the Titanium PowerBook G4 ; between 2003 and 2006, the Aluminum models were produced.

When the Aluminum PowerBook G4s were first released in January 2003, however, only 12 and 17-inch models were available.

The first generations of the PowerBook G4 were announced at Steve Jobs ' keynote at MacWorld Expo in January 2001.

They were just 1 inch ( 25 mm ) deep, 0. 7 inches ( 18 mm ) shallower than their predecessor, the PowerBook G3.

The PowerBook 190 series, PowerBook 5300 Series, PowerBook 3400c, and original PowerBook G3 shared the same interchangeable floppy drive module as a standard feature.

The original PowerPC 601, like the original 68040 before it, produced too much heat and consumed too much power for Apple to use in any laptop, but by the end of 1995 the more efficient PowerPC 603e had been developed, which was featured in the Duo 2300c and its full size companion, the PowerBook 5300 series.

* Supported Computers: Power Macintosh G3, G3 B & W, G4, G4 Cube, iMac, PowerBook G3, PowerBook G4, iBook ( The original " Kanga " PowerBook G3 was the only G3-based Mac not to be supported by Mac OS X ).

* Kanga, the internal development codename for Apple's PowerBook G3 computer, now used to differentiate between the original and later models

The PowerBook G4 had two different designs: one enclosed in a titanium body with a translucent black keyboard and a 15 " screen ; and another in an aluminum body with an aluminum-colored keyboard, in 12 ", 15 ", and 17 " sizes.

The PowerBook 5300, while highly anticipated as one of the first PowerPC-based PowerBooks ( along with the PowerBook Duo 2300c, both released on the same day ), had numerous problems.

The 12-inch PowerBook's screen did not use the same panel as that used on the 12-inch iBook, while the 17-inch PowerBook used the same screen as that used on the 17-inch flat-panel iMac, but with a thinner backlight.

) The Kanga was on the market for less than 5 months, and is largely regarded as a stopgap system that allowed Apple to ship G3 PowerBooks in a predexistent Apple design while Apple prepared its more revolutionary PowerBook G3 Series.

All PowerPC Macs from the iMac, the iBook, the Blue and White Power Mac G3 and the Bronze Keyboard PowerBook G3 forward are New World ROM machines, while all previous models ( including the Beige Power Mac G3 and all other beige and platinum Macs ) are Old World ROM machines.

All Macs prior to the iMac, the iBook, the Blue and White Power Mac G3 and the Bronze Keyboard PowerBook G3 use Old World ROM, while the iMac, iBook, Blue and White G3, and Bronze Keyboard PowerBook G3, as well as all subsequent models until the introduction of the Intel-based EFI Models are New World ROM machines.

The first displays were designed to match the colorful plastic of the Power Mac G3 and later the Power Mac G4 while the second revisions were designed to match the more professional aesthetics of the Power Mac G5 and PowerBook G4.

The discrepancy in time is particularly noticeable when it comes to computers ; in High Wizardry Nita's family obtains a brand new " Apple IIIc +," apparently modelled on the Apple IIc + of 1988, while less than a year or two later in Wizard's Holiday Dairine's computer Spot is apparently imitating an Apple Titanium PowerBook.

At the museum's PDP-1 restoration celebration in May 2006, Alan Kotok said his Macintosh PowerBook G4 laptop was 10, 000 times faster, came with 100, 000 times the RAM and 500, 000 times the storage, was 1 / 2000 the size, and cost 1 / 100 as much.

The PowerBook 100, however, did not sell well until Apple dropped the price substantially.

The PowerBook 190, released in 1995, bears no resemblance to the rest of the PowerBook 100 series, and is in fact simply a Motorola 68LC040-based version of the PowerBook 5300 ( and the last Macintosh model to utilize a Motorola 68k-family processor ).

In 1992 Apple released a hybrid portable / desktop computer, the PowerBook Duo, continuing to streamline the subnotebook features introduced with the PowerBook 100.

The " Lombard " appeared in 1999, ( AKA: Bronze Keyboard ) a thinner, lighter, and faster ( 333 or 400 MHz ) PowerBook with a longer battery life and had both USB and SCSI built in and was a New World ROM Mac, and then the " Pismo " in 2000, which replaced the single SCSI port with two FireWire ports, updated the PowerBook line to AGP graphics, a 100 MHz bus speed, and DVD-ROM optical drives standard, in addition to dropping the " G3 " from the PowerBook name.

Every Macintosh and PowerBook introduced from 1988-97 ( with the exception of the PowerBook 100, PowerBook Duo series, and PowerBook 2400c, which offered a proprietary external floppy drive as an option ), had a built-in SuperDrive floppy drive.

The Macintosh Portable and PowerBook 100 can run Macintosh System 6. 0. 4 through System 7. 5. 5.

Likewise the trackball was reduced in size from even that used on the PowerBook 100.

With PowerBooks being restricted to 68030s for several years, Macworld reviewers conceded that the best choice for power users was the PC-compatible Texas Instruments 80486 notebook, rather than the top-of-the-line PowerBook 180.

The PowerBook 190cs, the last 68k-based PowerBook, was discontinued in October 1996.

This same identification scheme was used in the iMac, PowerBook, and iBook lines of Macintosh computers.

Other past Macintosh lines which used PowerPC processors include the PowerBook 5300 and later models, iMac, iBook and Xserve as well as the Apple Network Server, which was not technically a Macintosh.

The PowerBook is a line of Macintosh laptop computers that was designed, manufactured and sold by Apple Computer, Inc. from 1991 to 2006.

The PowerBook line was targeted at the professional market, and received numerous awards, especially in the second half of its life, such as the 2001 Industrial Design Excellence Awards " Gold " status, and Engadget's 2005 " Laptop of the Year ".

When attempting to increase processing power, Apple was hampered by the overheating problems of the 68040 ; this resulted in the 100-series PowerBook being stuck with the aging 68030 which could not compete with newer-generation Intel 80486-based PC laptops introduced in 1994.

In 1993, the PowerBook 165c was the first PowerBook with a color screen, later followed by the 180c.

In 1994, the last true member of the 100-series form factor introduced was the PowerBook 150, targeted at value-minded consumers and students.

The PowerBook 500 series was the mainstay of the product line until the PowerBook 5300.

The 500 series was the first PowerBook to feature PCMCIA slots, although this was an optional feature which required the user to sacrifice one of the two available battery slots to house the PCMCIA expansion cage.

The PowerBook 500 series was released as Apple was already moving its desktop machines to the PowerPC processor range, and a future upgrade was promised from the start.
