Google and Lenovo released the first Project Tango handset this week at CES. The phone includes an array of sensors that let apps cover real-world objects with digital overlays. It's sort of like augmented reality on steroids. Project Tango needs apps, and Google us willing to pay.
This week, Google announced a new top-level domain for mobile apps needing a home on the web: .app. Google sees many benefits for apps owning some space on the web, and its main selling point for the .app TLD is the built-in security requirements to communicate with an .app website.
