So enough armchair critiquing, here's what might help this. Add export presentation functionality to Flash or QuickTime. Seriously. Both formats are relatively cross-platform, and would mean I could use a standalone player to launch the presentation full screen and not have to rely on Keynote/PowerPoint. Secondly, I know it's 2008 and we have Internet access via cellphone and wifi. But don't assume presenters will have access to a reliable, fast, connection. Maybe in 2015 I'll look back at my comment and laugh because fast wireless Internet access is near ubiquitous everywhere and my criticisms no longer apply. But my criticisms are born out of a sense of pragmatism. Never have I gone into a presentation assuming Internet access would work. At almost every conference there's at least a couple of presenters that get caught out because a site is down, the Internet connection is flaky, or about 50 people in the audience are blogging and saturating the bandwidth until it is slow as molasses.
