hi there,

According to the sources within Microsoft, the next Operating System will be cloud based. Rajan Anandan, MD of Microsoft India also added that “All new products from here on will be offered over the cloud, as well as on-premise. That’s a core strategy that we have adopted now”

so let's us look forward to the new powerful Windows 8.

Cloud is just a name of a technology. I don't know how good cloud is, (I guess many users can't feel that good neither). But I know, if Windows 8 gives us a free online backup space, it is really good.
