Not surprised. Nothing surprises me, about what the iPhone is capable of these days. What surprises me is my lack of foresight, not seeing what that phone would become when it was introduced, and buying Apple stock. I was kinda put off then my son-in-law showed me his phone back then, and said the most popular app was the "Fart App," which made wonderful amusing flatulence sounds.
I borrowed my client's EMF detector back in '90 to test EMF in my bedroom because a transformer was on telephone pole right outside my window. EMF was not noticeable, which surprised me.
