I agree with you, for the way you use calanders and tasks, but that's just it, that's how you and probably one group of people use it. I don't believe the phone would be as succesful as it is, had it only been designed for one group of people to use in one way. It needs to be adaptable for various uses, to some degree. And this is a seeming very simple fix, and I think just as important to a whole other group of people.
Peace!
