Imagine a tablet in split-screen mode, one app on the left, one on the right. And imagine the tablet defaults to this multi-tasking mode and sometimes allows an app to go full-screen.
Now imagine that tablet folds in half to show you one app, and then it fits into your pocket.
This is one way to think about what the new Surface Duo is.
Made by Microsoft, it’s a new 2-in-1 tablet/phone instead of a tablet/laptop.
