The Palm Pilot team, aware of this danger, took a hard line against feature creep. When the team began its work, in the early 1990s, personal digital assistants (PDAs) had an unblemished record of failure. Apple’s famous debacle with its Newton PDA had made other competitors gun-shy.
One of the competitors on the PDA market in 1994 looked like a malnourished computer. It was a bulky device with a keyboard and multiple ports for peripherals. Jeff Hawkins, the Palm Pilot team leader, was determined that his product would avoid this fate. He wanted the Palm Pilot to be simple. It would handle four things: calendars, contacts, memos, and task lists. The Palm Pilot would do only four things, but it would do them well.
