May 10, 1999: The third-generation PowerBook G3 comes in 20% slimmer and 2 pounds lighter than its predecessor, but most people remember the laptop for its “bronze” keyboard.

Although it doesn’t get a new name to distinguish it from previous laptops in the lineup, fans call it “Lombard” after Apple’s internal code name (or simply the “PowerBook G3 Bronze Keyboard”).

May 8, 1997: Apple launches the PowerBook 2400c laptop, a 4.4-pound “subnotebook” that’s the MacBook Air of its day.

The PowerBook 2400c predicts the rise of speedy, lightweight notebooks, while also paying tribute to Apple’s past. Its design echoes the original PowerBook 100. Even years later, it remains a cult favorite among many Mac users.

August 16, 1993: Apple ships the PowerBook 165, a lower-cost, grayscale version of the PowerBook 165c, which was the company’s first laptop to offer a color display.

The new model lacks the most attention-grabbing feature of the 165c, but it also brings its own claim to fame. The PowerBook 165 is Apple’s most affordable laptop yet.
