I came across this article not long ago.

It talked about Netscape's plan to release an operating system called Netscape Constellation - a browser aim for internet, which gives the internet application function as well.

The article was dated March, 1997.

Since then, Netscape's browser market share had fallen drastically to Microsoft's IE.

And then, the plan for the OS was never heard.

12 years later, Google announced Chrome OS.

This time there were a lot of support from hardware manufacturers, users etc. Some even forecast that it could threaten Microsoft's Windows platform (as internet application is taking the trend now)

Well, that's really a wrong timing for Netscape.
