Microsoft working on Windows replacement

Indisputably the dominant computing platform of choice, the Windows Operating System looks set to remain that way for many more years to come. Microsoft is certainly not content to take things sitting down though. Already, its own research lab is cooking up a new operating system that is nothing less than a radical departure from the current paradigm. Called Midori, it does away with dependencies tying Windows to a single PC, with a design that centers on the Internet. Many believe that the idea behind Midori is to create a lightweight operating system that can easily be mated to serve as a portable host for compartmentalized applications. If that is true, it sounds like Microsoft's answer to the threat posed by the increasing use of virtualization on the desktop.
