I use it to share files between devices. I can also share urls between devices. Clipboard history is automatically synced between devices.

I can also use it find my phone if I misplace it somewhere.

It is also possible to run custom commands. You can shut down or restart your pc from your phone. My favourite is the screenshot command, after the screenshot is captured, it is automatically transferred to my phone. A really handy feature.

There is more. You can also play pause and control the volume of a video playing on your phone or on your laptop from the connect app. Your device can even be used as a touchpad.
