If memory serves, and I know that Search here does, the noBounds project was an unfortunate consequence of one of the research lab closings Nokia had last year. However, there was a person from that team that came here talking about noBounds being something near a commerical possibility. Nothing has been said since, but I know that its one of the later threads in the Search in which this was talked about.

Several folks (myself included) wanted this for the N800/N810. To have it period would be great for mobile devices as a whole, but for this specific genre, it would be class-defining...

...that being said, it would force developers to think about non-handheld contexts for their UIs too. And the earlier tablets didn't make that so easy. It could be a good deal easier with Qt/Maemo/MeeGo and the N900, however, that's yet to have been seen.
