I quite often use a great article on Presentation Zen that compares the presentation styles of Steve Jobs and Bill Gates as an example when discussing how to give a good presentation. The original article is now about two years old, and in that time things have moved on in terms of the software available. Has the new software made any difference? Check out this new article on the same subject which compares a couple of recent presentations, and includes links to videos of the presentations and copies of some of the slides.
