The Adobe Macromedia merger is now a fact. I don't think it is just an Adobe takeover although the Macromedia name has gone. My impression is that the Adobe people have more confidence in the future of the Macromedia products than in the Postscript backlog they were working with. PDF was a way to transition from the printed page to the web. Maybe this is no longer exciting in San Francisco.
I am still mostly interested in PDF and I think it has a long way to go. Bandwidth like the future is not evenly distributed. On the planet print is still the main way of communicating.
Open Office and Microsoft Office 12 will both create PDF so it will stay around even if 'design' tends towards animation.
