The Palm Pilot, introduced by Palm Computing in 1996, was the handheld that finally made the personal digital assistant a mass-market product. Earlier attempts at pen computing, including Apple’s Newton MessagePad and a wave of “pen tablet” machines, had stumbled on bulk, price, and unreliable handwriting recognition. The Computer History Museum describes the PalmPilot as “the first wildly popular handheld computer,” a device that succeeded precisely because it was designed as an accessory to the personal computer rather than a replacement for it.
The product grew out of work by Jeff Hawkins, who had earlier designed tablet computers at GRiD Systems. According to the Computer History Museum, Hawkins prototyped the device by carving a block of wood to pocket size and carrying it into meetings with a chopstick as a pretend stylus, counting the steps required to perform common tasks. That discipline produced a tightly focused design whose virtues the museum summarizes as “seamless one-button synchronization with the PC, handwriting recognition that really worked, easy-to-use organizer functions, fast responses, pocket size.”
Two features set the Pilot apart. The first was Graffiti, a handwriting system that, rather than trying to read ordinary cursive, asked users to learn a simplified single-stroke alphabet entered in a fixed box. It was a gamble that people would learn a new way to write in exchange for accuracy, and it paid off; expert users could reach around 40 words per minute. The second was HotSync, the one-button synchronization that kept the handheld’s calendar, contacts, and notes mirrored with a desktop PC, reinforcing the idea that the handheld should complement the computer.
Commercially the device was a hit. The Computer History Museum notes a price of around 299 dollars and roughly one million units sold within the first 18 months. The platform was extensible through third-party applications, and the official Palm OS SDKs (archived versions 1.0 through 5.0 survive in community repositories) let outside developers build software that loaded onto the device, seeding a large catalog of handheld applications.
The Pilot established the template for the pocket organizer and, more importantly, for an entire app economy on a constrained mobile device, a pattern that BlackBerry, Symbian, Windows Mobile, and ultimately the iPhone would all build on. Its name was later shortened to “Palm” after a trademark dispute with the Pilot Pen Corporation, but the original Palm Pilot remains the device that proved handheld computing could be both useful and popular.
