Are you curious to know a little more about the early days of the PDA? If so, Evan Koblentz has written a detailed history of the PDA from 1975 to 1995. Specifically, my intention is to clarify which companies premiered each of the primary front-end features that are considered standard in modern devices, as of the mid/late-1990s commoditization trend.
From the early days of HP calculators to Apple coining the term “personal digital assistant” to the Pilot 1000, the article covers a wealth of models (many with pictures) that may trigger some fond memories.
