This is a great piece of tech history about Motorola and Martin Cooper (the inventor of the first cell phone). I never knew that the first public cell phone call (on the DynaTAC 8000x) was essentially an "in-your-face" moment to Cooper's rival, Joel Engel.

I think the most interesting piece of the story is when he notes "how useless having a million apps is. How does a person sort through a million apps and find the one that is suitable for them? The concept of the app is wrong!" I have to admit, I hadn't thought like that before, perhaps because we are constantly designing at the app level and not the systems level. About a minute later, Martin says, "instead of us looking for apps, the app ought to find us... I never said that before... I love that."
