How is this different than say, walking around your house with your smart phone recording video, and then pushing a button to upload it to your real estate ad? Advantage Tango: The user could manually navigate the virtual house. Advantage Standard Video: Improved accuracy, no wonky 3D model and texture recreations, but actual video. Runs on low end hardware, no fancy plugins required. You can turn on lights, open drawers, show how a sliding door works, or how the fridge looks inside. If I had my choice, I'd take video over Tango for real estate. Even so, video has been around for ages, it's dead simple to create and upload, yet never used. Therefore, if video hasn't taken off in the past decade, I can't see Tango having any noticeable impact on the market.
