There was a surprise announcement from Microsoft at its event showcasing new products.
The Microsoft Surface Duo, a folding phone, made its debut Wednesday morning.
It is an Android device and features two side-by-side 5 1/2 inch displays connected by a 360-degree hinge.
The Surface Duo incorporates elements of Windows 10-X, a new operating system meant for hybrid devices.
It can also run two different apps at the same time on the separate screens.
The Duo will launch in late 2020, in time for the holiday season next year.
