Silly article. Microsoft won't disappear overnight. Unless, perhaps, they decide to hire Leo Apotheker after he finishes HP off. ;-)

Now, seriously, browser-based interfaces to cloud-based apps and data will be Microsoft's demise - they'll make the OS irrelevant, commoditizing its cash-cow. Will they be able to reinvent themselves? Probably yes. Will they ever be a dominant player again? Certainly not.

Would I be happier in a world without Internet Explorer, Sharepoint and Exchange? You bet!
