Microsoft Courier - The tablet Microsoft shut down

Recent rumors has it Microsoft was working on two tablets simultaneously, one inspired with a "think different" approach lead by J Allard and another as an evolution of Windows lead by Steven Sinofsky.  In short, Balmer had a tough decision and resorted to Bill for helping him making the best decision.  Bill, having the natural affinity to Windows, killed the think different version because it was not designed with Windows in mind didn't integrate with Office at it's core.  This is the first time I see the promotional video of the think different version -- Microsoft Courier; not too shabby.
