Microsoft is back to selling smartphones for the first time since it abandoned its mobile business more than four years ago. The company began taking orders on Wednesday for the Surface Duo, a new dual-screen Android device that costs $1,399 and begins shipping in September.
Microsoft is pitching the Duo as a more useful tool than a conventional smartphone, since it enables users to multitask with two separate apps or web pages at a time. CEO Satya Nadella, for instance, uses one screen to take notes and the other to read a book on Amazon's Kindle app. The Duo has two 5.6-inch displays and, when opened like a book, is slim with 4.8 millimeters thickness, making it what the company says is the thinnest device on the market.
