The Origins of Handheld Computers

The concept of handheld computers can be traced back to the early 1970s when Hewlett-Packard introduced the HP-35, the world's first scientific pocket calculator. This groundbreaking device laid the foundation for more advanced handheld devices, such as the Psion Organizer, which debuted in 1984 as the first pocket-sized computer.

Throughout the 1980s and 1990s, various companies such as Apple, Palm, and IBM developed and launched their own versions of handheld computers, which were often referred to as personal digital assistants (PDAs). These devices were equipped with basic computing functions, such as calendar management, note-taking, and email capabilities, and allowed users to stay organized and connected on the go.

Types of Handheld Computers

Over the years, handheld computers have evolved into different forms and types, catering to the specific needs of users across various industries. Some of the most common types of handheld computers include:
