In 1991, Apple introduced the PowerBook 100 priced at $2,500. Blue-collar hourly compensation at the time was $14.93, so the time price was around 168 hours. Today you can pick up a 13.3-inch MacBook Air for $999. With blue-collar hourly compensation around $36.50 today, the time price is just over 27 hours. You can get six MacBook Airs today for the time price of one PowerBook 100 in 1991.
The PowerBook 100 weighed 5.1 pounds and featured a 640×480 monochrome LED screen, 2 megabytes of memory, and 20 megabytes of storage. The battery was good for three hours. The MacBook Air has 13.3 times more pixels (in millions of colors), 4,000 times more memory, and 12,800 times more storage than the PowerBook 100. It weighs 45 percent less, and the battery lasts six times longer. The MacBook Air has Wi-Fi, a 720-pixel camera, and stereo speakers and comes with 32 apps ranging from music programs to spreadsheets.
While it’s hard to make a direct comparison, a simple way to do an analysis is to ask MacBook Air users how many PowerBook 100s they would need to give up their one Air. Most users now think the PowerBook 100 has negative value due to the disposal costs. That would make the MacBook Air infinitely more valuable.
