From the moment computers became a part of our daily lives, the race to make them smaller, faster, and more portable began. In this post, we will take a deep dive into the history of early handheld computers, exploring their groundbreaking features and the impact they had on the world of computing. So, sit back, relax, and join us as we travel through time, witnessing the remarkable evolution of these fascinating devices.

The Dawn of Handheld Computing: The HP-35

The first significant milestone in the development of handheld computers came in 1972 with the release of the HP-35, the world's first scientific calculator. Designed by Hewlett-Packard, this revolutionary device allowed users to perform complex calculations on the go, making it an instant hit among engineers, scientists, and other professionals. The HP-35 set the stage for future handheld computers, proving that powerful computing capabilities could be packed into a small, portable device.

The Rise of Pocket Computers: The Psion Organiser

In 1984, British company Psion released the Psion Organiser, the world's first pocket computer. This groundbreaking device featured a small keyboard, a one-line display, and the ability to store and retrieve data. Users could also write simple programs in the device's built-in programming language, making it a versatile tool for a wide range of applications. The Psion Organiser marked the beginning of a new era in handheld computing, as more and more companies began to develop their pocket computers.

The Power of Pen Computing: The GRiDPad

The late 1980s saw the introduction of pen computing, a concept that would forever change the way we interact with handheld devices. In 1989, GRiD Systems Corp. released the GRiDPad, the first tablet computer that utilized a stylus for input. The device featured a 10-inch monochrome display and ran on the MS-DOS operating system. The GRiDPad's innovative pen input system paved the way for future touchscreen devices, including smartphones and tablets.

The Birth of the PDA: The Apple Newton

In 1993, Apple released the Newton MessagePad, a device that would become the blueprint for the modern personal digital assistant (PDA). The Newton was the first handheld computer to feature handwriting recognition, allowing users to input data directly on the screen using a stylus. The device also offered a range of productivity applications, including a calendar, address book, and notepad. Although the Newton was ultimately discontinued in 1998, its innovative features and design would inspire a new generation of handheld computers.

The Palm Pilot Revolution

In 1996, Palm Inc. released the Palm Pilot 1000, a device that would redefine the PDA market. The Palm Pilot featured a compact design, a monochrome touchscreen, and a suite of productivity applications. The device also introduced the concept of "Graffiti," a shorthand writing system that allowed users to input data quickly and accurately using a stylus. The Palm Pilot's success spurred a wave of competitors, leading to a thriving PDA market in the late 1990s and early 2000s.

The Emergence of Pocket PCs: The Compaq iPAQ

As the new millennium began, a new breed of handheld computers emerged: the pocket PC. In 2000, Compaq released the iPAQ, a powerful and versatile device that ran on the Windows CE operating system. The iPAQ featured a color display, a powerful processor, and expandable memory, allowing users to run a wide range of applications. The device's compatibility with Microsoft Office and other popular software made it a popular choice among professionals, further blurring the line between handheld computers and their desktop counterparts.

The Smartphone Revolution: The BlackBerry

In 2003, Research In Motion (RIM) released the BlackBerry 6210, a device that combined the functionality of a PDA with the convenience of a mobile phone. The BlackBerry featured a full QWERTY keyboard, making it an ideal tool for business users who needed to send and receive emails on the go. The device's success marked the beginning of the smartphone era, as more and more companies began to integrate phone capabilities into their handheld computers.

The iPhone: A New Era of Handheld Computing

In 2007, Apple released the iPhone, a device that would forever change the landscape of handheld computing. The iPhone combined the functionality of a phone, PDA, and iPod, offering users a seamless and intuitive experience. The device's innovative multi-touch display and sleek design set a new standard for handheld computers, inspiring a wave of imitators and competitors.

As we look back on the history of early handheld computers, it's clear that these devices have come a long way since the days of the HP-35. From scientific calculators to pocket computers, PDAs to smartphones, each generation of handheld devices has brought new innovations and capabilities, forever changing the way we work, communicate, and interact with the world around us. The future of handheld computing is undoubtedly exciting, as we continue to push the boundaries of what these powerful and portable devices can do.
