SoapBox="YouTube" by Microsoft

As usual, when something is getting successful, Microsoft has to copy it.
So, Microsoft is going to release in the coming weeks its version of YouTube, its name: "Soapbox" (http://soapbox.msn.com).
It is currently only a beta version, but it expects to grab some of the visitors of YouTube (35 millions/month).
If IT and multimedia are competitive markets where everybody is trying to do the same thing than the other one, especially if it is successful, one has to admit that Microsoft does not know how to innovate, copying must be in their genes... the problem being that in most cases it is a "cheap and dirty copy".
When was it the last time that Microsoft released something original? I mean new, coming directly from their huge R&D Department and being successful?
