The presentation today Tools of Change conference also announced that Inkling will soon be available in HTML5 browsers. So, Habitat will cover an even larger spectrum in the near future... not just the iPad.
The OP, written by Inkling's CEO, also says: "I also previewed Inkling for Web, which will make all of Inkling’s great interactive content available in any web browser."
They seem to be doing some really interesting stuff with their technology, and it's the first thing I've seen that would make me reconsider just using straight HTML.
I reckon this is about as close as we have to a new type of press: http://h10088.www1.hp.com/cda/gap/display/main/index.jsp?zn=...
It's one of the presses that print-on-demand operations use (this one's made by HP, but I believe Xerox make them too). The video is nifty :)
