Ghent PDF Group still on about PDF. I have found a meeting on 19th about PDF at the Knowledge Centre

Many will agree that PDF had once seemed to be the ideal format for exchanging and publishing information – and has undoubtedly been a tremendous boon to premedia workflows. In this session, Zwang will discuss its relevance in the new world of information publishing. As new electronic distribution tools continue to debut, many wonder if print is being replaced by these new technologies; such as smartphones, tablets, pads, and more.

So it could be that the PDF world accepts that other formats have a role. Reflow is an issue on small screens, also the time it takes for files to load. Adobe is still not advertising where it will be so I conclude that they don't see the show as that interesting. Postscript and PDF are not growth areas. Flash will be discovered online so there is no need to talk about it at shows.

Meanwhile Microsoft offer online versions of Office roughly similar to Google Docs. The era of desktop software may be coming to an end except for special interests such as Creative Suite.
