You would think that the former CEO of Google and current Executive Chairman of its parent company would be using a Nexus smartphone, or at least some kind of Android device, but as it turns out, Eric Schmidt uses an iPhone. Schmidt was in South Korea this week to watch the historic battle between a Google-made artificial intelligence and the top-ranked Go player in the world, and while he was there, he was spotted using an iPhone to take a picture. Considering how he used to use a BlackBerry while serving as the CEO of Google, this isn’t all that surprising, but it’s still a bit odd.
