You know it’s the future when digital db meters cost $1.

I just bought a basic digital sound level meter. For $1. Three years ago, it likely would have cost me at least $60. But because the one I just bought uses my iPhone as a platform, the vendor cuts out at least 98.3% of the previous retail price – i.e., the cost of designing, manufacturing, delivering and having retailers stock a physical, single-use device.

How will Radio Shack survive if not by selling apps?
