The Dog told me Steve Gillmor's InfoRouter ZDNet.com: "First, Office is dead. The chorus of 'Gillmor is nuts' from Scoble, O'Kelly, Carr et al in no way refutes the facts. I may be nuts, but then so is Bill Gates, who as Scoble pointed out so presciently produced his 2010 future scenario keynote entirely without PowerPoint. Who needs a presentation program when they can demonstrate what they're talking about with live objects? As Lotus ScreenCam pioneered many years ago, just record the instructions to the screen and audio drivers rather than the bitmaps."
Hey Steve -- these may be separable issues (just kidding...), but I don't recall saying I think you are nuts. On "Office is dead," however: it's more likely to be a cumulative build, i.e., Office-type applications will continue, even with widespread and cost-effective wide-area wireless (which I for one am not counting on being pervasive "real soon now"), primarily to take advantage of local storage, processor, etc. Certainly there will also be software-as-a-service alternatives as well, with some of the most popular probably coming from Microsoft, as part of Office Live and Windows Live.
BTW if you want to see a compelling application of live objects and seamlessly integrated tools, check out Adobe Breeze sometime.
