Mac OS X turns ten this week. That's ten years since the first public release of the jewel in the crown that signifies Apple's rise from the brink of death with a modern and "revolutionary" clean slate. But it wasn't the first time a piece of Apple software saved the company -- that honour goes to the original Macintosh operating system: System 1.0. Read on to learn how Apple changed its fortunes and revolutionised computing back when the terms GUI and mouse were foreign concepts.

The core of the Macintosh experience was never the attractive industrial design, the sense of superiority, or the use of a strange one-button mouse -- although those elements were vitally important. From the very beginning, even before the first Mac hit the market in 1984, right through to the latest iMac or Macbook models, the Macintosh was about providing the most accessible and intuitive interaction possible between humans and computers.

Computers should be easy to use, with user interfaces that Jack and Jill Smith who just walked in off the street can use comfortably with almost no instruction. Gestures, not typed commands; desktops, buttons, and icons -- not command lines, carriage returns, and terminals -- have clear analogies to things from everyday life that people without a degree in computer science can understand. This is at the heart of the Apple philosophy, as it has existed since that fateful trip to the Xerox labs in December 1979.

When Windows 95 came out, I didn’t care. Sure, I was just a kid, but I could clearly see that it was inferior to System 7.5.5. Years later I learned this isn’t strictly true -- although the feature gap was almost non-existent (despite what Windows’ marketing suggested), they each possessed different strengths and weaknesses. But all I saw was an ugly interface, a continued reliance on the dated DOS back-end, and the infamous blue screen of death. And games still looked better on the Mac, even with the aging hardware.

It was like a window to another dimension, where somehow everything bad reigned supreme over all that is good. I didn’t like it. I wanted to close the shutters and pretend there was no other dimension. But there was no escaping Windows, and I soon came to terms with my aversion for the OS, thanks in large part to a game called Civilization II and a little thing called the Internet.
