I honestly could never get into a productive relationship with graffiti, but glad it worked for you. But I guess the point of the other posters is that it should always be technology aiming to bend to human needs not the other way around.Palm graffiti says hello. Technology was developed (specific rules of how each character were written), people learned how the technology worked (people had to conform to the rules), everyone was happy.
This may not be achievable at the moment but should be the goal!
BTW...if you'd be speaking german, your perception of siri would be completely different...no wolframaplpha, pretty bad "heard correctly" rate.
So taking your point of view, I should learn to speak english? Or better yet, we all should learn to speak Ido (http://en.wikipedia.org/wiki/Ido_%28language%29) and be done with it.
While this may be a valid approach, I don't like the Idea of man bending it's knee to maschine more than we already do ;-)
