I wonder what the learning curve is v. the time it takes each day to locate your keys, cat and those shoes you wear when you get up and the house is so cold you want to go back to bed.
Learning curve may win out. Only 18 days left for this app. http://www.indiegogo.com/sticknfind
I heard yesterday that the apple map app led several tourists to be lost in a large national park in Australia. One man was there for 24 hours until he could find a signal. There is no water in this particular park. Apple suggests that until the problem is fixed you use other means of getting terribly lost.
