Google Search for Release Date

I just discovered another special query that Google uses to return specific information, rather than just general search results:  Release Date.

Search for Photoshop CS2 Release Date and Google will clearly tell you that the release date was April 28, 2005.  Windows XP Release Date gets you October 10th, 2005.

I use the movie:Pirates of the Carribean style special movie search quite a bit; these sort of new feature that just shows up inside the queries you’re already making are excellent, and in my mind what really differentiate Google as the leaders in search.
