This information has actually been out for a while. I remember reading about 
it over a month ago, and lots of organizations are already fighting it. The 
problem is that if you read the patent application properly, it revolves 
around a specific way of changing desktops using a type of transition. So 
this is really an application for a patent that "improves" on prior art, not 
a patent that imitates prior art. That makes it a bit harder to disprove.

On the other hand, the specific way of changing desktops that Microsoft 
describes in this application HAS been done before, but only by this one guy 
who was working on 3D transitions for switching desktops. I forget what the 
software was called, but I'm pretty sure it was GPL'd.
