This problem sounds like a made-up problem. Nobody's cell phone app is going to cure cancer yet... but they ARE very useful for using cameras to deposit checks and file expense reports without any paperwork... I don't see what you're getting at... there is useless crap all over the place, everyone tries their hand if they are willing to do it, and if it's something that people want, they pay for it. If it's not, then they don't. The OP is clearly focused on one or two, or twelve apps or tech that are 'useless' but I wonder if they would stop a second and think just how fast the ENTIRE WORLD is changing right now... All the time.
