Does it surprise you to know that Windows is only about 9 years old? That it was released in 1990?
That version of Windows, of course, was called 3.0. There was a Windows 1.0 and Windows 2.0, but they were so pathetically, mind-numbingly bad that nobody even tried to use it. Windows 3.0 was different. It was merely incomprehensibly bad. But it was made by Microsoft, the company that gave us Dos 3.0, 3.1, and 3.2, and 3.3, and 4.0, of course, and 5.0 (the best dos ever), and 6.0, 6.1, and 6.2. And Bill Gates, at the press conference announcing the conception of Windows, warned that other graphical user interfaces wouldn't be compatible with future versions of dos.
In 1990, nobody could have believed that Windows would be so late, so bad, and so slow. Everybody thought that in a year or so, we'd all be happily clicking and dragging around on our IBM compatibles in Microsoft Windows.
Geoworks was released in 1990, and it ran great. It was a true graphical user interface with a remarkably functional core, and real multi-tasking. It ran happily on 2 MB of RAM and required very little disk space.
Just as it was set to take the world by storm, Bill Gates announced that Microsoft was almost ready to roll out it's own version, Windows, in just a few months.
Geoworks was destroyed, crushed by the announcement. Software developers switched to Windows, so third party applications dried up. Even worse, the investors pounded Geoworks' stock until it was pretty well wiped out.
It took five years for a truly functional Windows to emerge (Windows 95) and, even then, it still wasn't as reliable as Geoworks was in 1990. I run both Windows 98 and Windows NT on my desktop. They are both pieces of garbage, to put it bluntly. They are bloated, slow, bug-ridden, and annoying. Why do I use them? Because I make my living with computers. Everybody wants Office 97 and Quake and all the other Windows applications. I get paid to try to solve all the problems that shouldn't exist.
There are other operating systems: Linux, BeOs, OS/2, but few applications that run on them. These other OS's are strong, reliable, and fast, but Microsoft beat them off with sticks and stones. That is the legacy of Microsoft's strong-arm tactics over the last 9 years. The result has been disastrous, though few people seem aware of it. The loss of productivity due to problems with Windows must be phenomenal.
