Why use Amiga Forever when I have real Amigas? Yeah, I know, so that I can have a laptop. For some reason, I've never had much luck with emulators. When I do, they seem to run slow and just don't feel the same (I know that is subjective). But I'm happy to hear that you have had some luck.
As for PowerPoint, I wonder how many people realise how unnecessary it is. My talk is being given on a prehistoric word processor. I use a full screen preview mode for the presentation proper. Sure, I loose transition effects but I don't care about those seeming as I view it as style over substance (yeah, I know opinions will differ). From the looks of it, I can even embed audio and video so multimedia content is okay. :-D Some people use Adobe Acrobat (or Preview on the Mac) to the same end. But most people are convinced PowerPoint is the only way to go ...
