Samsung's new DeX dock wants to turn your Galaxy S8 phone into a desktop. It can access specially optimized versions of select Android apps in order to give you a full-screen experience that's surprisingly PC-like.
A handful of Android apps are already optimized for this desktop DeX view, including the default internet browser and Microsoft Office. That means you can run multiple apps at once and grab the corner of each window to resize, just like on a PC. Apps that are not DeX optimized will open in a phone-shaped window.
