Michael Steeber, 9to5Mac:

A 20th anniversary is a milestone worthy of celebration in its own right, but even more so when describing a computer. Few technology products boast such a feat in an industry where changing customer preference and exponential technical advancement can quickly obsolete even the most well-considered plans.

This Sunday, Apple’s iMac line joins the 20-year club. Its ticket to entry is two decades of valuable lessons and ideas that tell the recent history of the personal computer industry and reveal Apple’s priorities and values. The iMac’s timeline tells many stories – some of reinvention and business strategy, others of software and hardware.

Perhaps none are more significant than the iMac’s design story. Explorations of color, form, material, and miniaturization have marked significant breakthroughs throughout the years. On this anniversary week, we’ll take a look at the design evolution of the iMac.

Really nice, long look at the evolution of the iMac. Well done.
