Google unveils ARCore, its answer to Apple’s ARKit,, which allows augmented reality to hundreds of millions of Android phones, and no Tango required. From the demos on the web, it seems ARKit provides superior qualities. However, Apple is always within a closed eco-sytem; unreachable to many (like me ). However, I am really worried about these 2 devices recently announced from Lenevo and Asus. All their pain in vain now. So frastrating to the developers and manufacturers.
