What's holding back presentation software?

Bob Sutor - I can’t think of one thing I do with presentation software today other than creating PDFs that I didn’t do ten years ago. We have Microsoft PowerPoint, we have OpenOffice.org Impress, and IBM’s Symphony. Over on the Mac we have Keynote. Toss in a few others such as KOffice and we have the office productivity market. These all have value to their users though if they don’t support ODF, the Open Document Format, in a first class way, I don’t care too much about them. On a regular basis I use Symphony and to a much lesser extent OpenOffice.org and Keynote.
