I got my first iPad in 2011 and went to see my grandmother up in Durham, North East England, who was in her 90s. My wife is Chinese and was in China with my daughters at the time, and we did a Skype call. At first she literally could not believe what she was seeing. It took me several times to explain that this was actually them, right now in China, and they could talk back to her and it wasn't just a recording or some sort of trick.
