PC

1973

Be it a desktop, laptop, tablet or smartphone, the average person owns at least one personal computational device, for performing a variety of tasks. Whether it’s for writing letters, receiving mail, checking the weather, making phone calls, shopping, playing games, calculating sums or booking a holiday, computers can handle it — and a whole lot more. Indeed, the empowering qualities of the PC are massive and it is easy to see why many argue it’s the most important device on Earth.
