Neat. I always love reading these, and performing them informally with relatives of mine when I get the chance. I don't fully agree with all of your proposed solutions (e.g. I think the unintuitive nature of the tabs interface in Safari can be attacked at a more fundamental level, and demonstrated explicitly the first time, as opposed to a separate 'mode' that is really an interface band-aid), but enjoyed reading it quite a bit. The fact that several of the stock 'data app' icons (weather, stocks, clock), really do imply a live data display, when in fact the icons are static, had never occurred to me before.
