Consider the Teams Display as a companion device to work alongside your laptop, an extension to allow you to keep your messages and appointments in view while coordinating to give you the best experience between both devices for example
Read a message on the device, one button to start a reply on the laptop
Join a meeting with the audio/video and video on the device, shared content or your own screen sharing on the PC
View a file, one click to open it to edit on the PC
This new class of device is certainly very interesting.
