Microsoft had its annual product event on Wednesday.

Microsoft made a surprise announcement Wednesday of a new two-screened Android smartphone, the Surface Duo. The device will launch in late 2020, in time for the holiday season. No pricing details were announced. The device features two side-by-side 5.6-inch displays that are connected by a 360-degree hinge. Once it's folded up, the Duo is small enough that it can fit in your pocket.

Microsoft said it partnered with Google to "bring the best of Android" to the device, while incorporating elements of Windows 10X, a new operating system meant for hybrid devices. It can also run two different apps at the same time. The phone opens up so that the second display can be used as a game controller or a keyboard. The second display can also function as a stand, enabling users to watch videos in landscape mode. "You can text, you can write, you can do what you want," said Panos Panay, Microsoft's chief product officer. "Make no mistake, this product is a Surface."
