Considering that Apple's patented nearly every tech concept under the sun, the revelation that it dabbled with a wearable display of some sort is hardly earth-shattering. According to Tony Fadell, Nest CEO and former Senior VP at Apple, Cupertino built a bunch of wearable tech prototypes but "didn't have time" to further develop them. Fadell describes Apple's approach as "visors, so it's like you're sitting in a theater," which sounds decidedly more like a VR headset or head-mounted display than something like Google Glass. Still, Apple dismissing one of Google's the year's most hyped concepts in favor of focusing on its streamlined device lineup? That's quite a burn to Mountain View.
