I just rewatched this video again: http://www.youtube.com/watch?v=MzgMMO-P9F0 - A preview of Microsoft Gemini in Excel 2010.
Why is it that when he says, 'we call them "Slicers"', I can hear Dr. Evil saying 'I call it a "LASER"' ;-)
Well, Gemini is now available as a Community Preview. You can get access to the Gemini CTP if you are a member of the Office 2010 Tech Preview by visiting http://www.microsoft.com/officebusiness/office2010/Default.aspx?vid=Gemini (if you go to that link, click on "Videos", there is a really bad "Project Gemini for Excel 2010" video that you can watch).
Is Gemini a "QlikView Killer"? I am not sure. All I can say is that my experience tells me that QlikView rocks compared to this demo. My experience also tells me that Microsoft are into marathon's, not sprints.
