Power Book 100 - Design

Design

Both the PowerBook 140 and 170 were designed before the 100 by the Apple Industrial Design Group, from March 1990-February 1991. The 100's styling was based on those computers and represents the first improvements to the PowerBook line as Apple benefited from the lessons learned in developing the more powerful models' enclosure. The 100 was designed between September and December 1990, and retained the same design elements, which were a variation on the Snow White design language Apple had been using since 1984. Specifically, 2 mm (0.079 in) raised ridges spaced 10 mm (0.39 in) apart intended to tie it into the existing product line.

Apple approached Sony in late 1989 because it did not have enough engineers to handle the number of new products that were planned for delivery in 1991. Using a basic blueprint from Apple, including a list of chips and other components, and the Portable's architecture, the 100 was miniaturized and manufactured by Sony in San Diego, California, and Japan. Sony engineers had little experience building personal computers but nonetheless completed Apple's smallest and lightest machine in under 13 months, cancelling other projects and giving the PowerBook 100 top priority. Sony president Norio Ohga gave project manager Kihey Yamamoto permission to recruit engineers from any Sony division.

Robert Brunner, Apple's head of industrial design at the time, led the design team that developed the laptop, including its trackball and granite color. Brunner said he designed the PowerBook "so it would be as easy to use and carry as a regular book". The dark granite grey color set it apart from other notebook computers of the time and also from Apple's other products, which traditionally were beige or platinum grey. The trackball, another new design element, was placed in the middle of the computer, allowing the PowerBook to be easily operated by both left- and right-handed users. The designers were trying to create a fashion statement with the overall design of the laptop, which they felt made it a more personal accessory, like a wallet or briefcase. Brunner said: "It says something about the identity of the person who is carrying it".
