Talk about bad timing:
Back in 1989 Steve Jobs created the NeXT and the NeXTStep OS, which was very the most advanced OS of its time, and maybe still is today. It was Unix-based, with a good interface based on solid object-oriented concepts, very, very easy to program and develop for.
A couple of months ago, I see a picture of the new Mac OS X interface: it's basically identical to the 1989's NeXT. That was really something that came ahead of its time. What's incredible is the fact that it was more than TEN years ahead. This shows how pitiful the software industry really is (regarding OS development), stalled by a non-demanding market. It's funny to see younger people impressed with old, forgotten stuff, and sad to see how good things get lost in time, and must be rediscovered. Computer renaissance.
What was most amazing, the thing was so much easier to use than any OS today, and the power of Unix was always underneath.
Obviously, the general PC buying population does not even know that these things existed. Although expensive for a home PC, a price tag of $15,000 was not outrageous. The NeXT cube was among the first workstations to come with sound and video support. It came with 17" monochrome screens (yep, no color). At that time, color was really a luxury. Like any Apple, you had to buy everything from them. After the initial jaw-dropping excitement, the thing got slow and expensive, and other companies, although never catching up, stole the market with the introduction of what became popularly known as 'workstations' (Suns 5/10, SGIs Indigos/Indys, and HPs 712/735), which had commonly 8-bit color (yes, eight).
Many people who were exposed to the NeXT, which then start coming in full color, with 21" monitors, continued to use the OS in more powerful and less expensive machines. The HP 712/60 was a popular choice. Keep in mind that at that time, Window 3.1 was still considered a toy in any professional/scientific environment. Aging software later killed the thing, and when win95 came out, everybody wanted Microsoft Office.
So, that's it. Twelve years later, we want the same features that were initially ignored, and later became inaccessible due to short-sighted consumers, and basically greed and poor marketing from the part of developers. PC World magazine put the NeXT in the top ten jokes of the PC industry, showing how misinformed and prejudiced some of those guys really are.
