Well, for one thing, it's free and opensource. It is completely compatible with all MS office filetypes. It actually includes features not found in office, such as the ability to export directly to a pdf (as opposed to using a pdf printer), and to export a presentation to a flash file. And their powerpoint-type program has much cooler transition effects not found in powerpoint. yeah, me neither...I need to clean it up. You notice the "unused icons" folder; I've done it once but installed more programs since then. btw Kevin, I didn't think Longhorn had been released Where did you get it?
