CNet has a good interview with Don Norman, designer extraordinaire and author. I’d highly recommend his books, they’ll get you thinking about design in new ways. Best passage from the interview:
“It was only the development of the factory, the industrialized revolution, then later the white collar revolution that everybody had to be in their offices at the same time.
But guess what? We’re now in a world society. Making sure we’re all in the office at the same time assumes we’re all in the same time zone…I think we’ll find interesting mixes of scheduled activities where everyone must be encountered in more flex time, more flexibility.”
