Microsoft's upcoming dual-screen Android phone, the Surface Duo, is getting ready for prime time. A couple of days ago, Israel Rodriguez spotted one in use on Vancouver's SkyTrain, tweeting an image that shows what appears to be a flash next to the front-facing camera. But as promised, there's more. In fact, there's a lot more. Rodriguez tweeted out a link to a YouTube video that includes several photos and some video footage, although there's no sound. It shows various use cases, such as playing games, checking email, using the device in various form factors, and more.
