wrote in with an article that describes Microsoft's strategy for future versions of Windows. It begins: "As we all know that Microsoft Vista was originally scheduled to be released in 2003, after two years of Windows XP, but it got delayed by over five years due to various reasons. Definitely, Vista is very very improved OS over the previous versions, but the delayed in the launch has cost Microsoft, billions of dollars. Now the question at the moment is, what exactly after Vista? Microsoft can't afford to wait another five years for an operating system. People are becoming more aware of the choices they have, and Linux is no longer a hobbyist OS, and that day isn't far away when it becomes simple enough to be a viable alternative to Windows. The competition is fierce. That is why, to stay at the top, Microsoft has planned a 'Vista R2', codenamed 'Fiji' which will be released some time in 2008. And after Fiji, there will be Windows 'Vienna'. Windows Fiji, will not be a totally different OS from Vista; but it will be an add-on. Whereas Vienna will be totally different from Vista."
