I have been presenting technical jargon for over 20 years (closer to 30) and I currently use a combination of Prezi, PowerPoint, and Camtasia. If this is a presentation that I am giving live, Prezi will be my shell. I will drop simple graphics directly into Prezi as images. More complex bullets, images requiring arrows and circles, etc. will be PowerPoint slides which I have saved (to import into the Prezi shell). And for highlighting code or text, I will bring PowerPoint slides up on my screen and record the screen with Camtasia... record my mouse highlighting code, annotating, zooming etc., and create small movie files that I'll bring into the Prezi shell. Once everything is in Prezi, I download it to my laptop and I'm ready to present. I might even screen record the entire Prezi (with Camtasia) and create a narrative sound file (using Audacity) that I will lay into the recorded presentation video. In this way, if there is a disaster (my flight is delayed; hangover, etc.) I can provide the audience a link to YouTube where they can watch my entire presentation in my absence. (It never hurts to sport your photo in your opening in the event that for whatever reason you're not there to present live.)
