We spend most of our days using computers at work, smartphones when we're out and about, and tablets and PCs at home. Technology, especially software, has become such an integral part of both work and daily life, it's hard to remember a world without it.

Software has made the impossible possible, and the laborious and tedious, fast and easy.
