This is a nice add-on for Microsoft Powerpoint that generates Flash (.swf) files from Powerpoint presentations. I find that this can be a very useful tool for educational purposes and let me make my Powerpoints more creative than just using the viewer. I could incorporate my Powerpoints into a blog or a webpage and be able to view it on any web browser with Flash. The only problem is that it's interface is inside of Powerpoint. This means I must use Powerpoint in order to generate the Flash files. I would much rather use OpenOffice.org Impress, but I can still make the Powerpoints inside of Impress and generate in Powerpoint. Overall the product seems very useful and is certainly worth the free download for you students out there. I wouldn't go to say it is worth $100 USD though. If I wanted to pay over $300 (iSpring - $100, Microsoft Office Standard - $ 325)for a Flash movie, I would just get Flash.
