I am an old Palm user, and developer... I miss a lot of the great productivity tools they had. The smartphones have still not caught up with the great programs on the Palm. They are good for the internet connectivity though (and the cameras are getting pretty damn good).
But everyone that knows me also knows there are half a dozen ways to contact me that does not involve phoning. I find that mostly old folks phone... I would rather use text or PM. I can carry on 3 conversations at once, easily, with messaging - can't do that on a phone ha ha
