Some are useful. Many frivolous. A bunch will waste your time. Not that there’s anything wrong with that. My Seinfeldian statement has to do with the scores of programs available free or for sale at the App Store for iPhone and iPod touch. It is the killer app many of us expected, even if the same cannot be said for every program in the joint. Some programs address the iPhone’s deficiencies — there are several audio recorders, for example. However, I still haven’t stumbled upon a program to let you shoot video via the iPhone’s digital camera.
