I remember when someone got a car to 100k miles - they called all their friends to see the car turn over to all 0's. They had to add oil before they left, and drove off in a cloud of smoke. They had to avoid puddles or the spray through the floors would get mud all over everybody...
Point is things advance. the first iteration might be as bad as you say, but they are likely to fix the bugs and make it better over time.
Well you are still paying orders of magnitude more than a pen and paper grocery list. For what in my mind is no new real functionality. Just the ability to get a bit lazier and think a bit less.
