Reported on back in March, the NexDock 2 is a pretty exciting accessory coming for any Windows 10 Continuum or Samsung DeX fan. The idea is to plug in via USB Type C and have the entire OS/UI extended to the lap dock screen (while the phone screen acts independently). Although this hasn't reached the production stage yet, prototypes exist and the folks at XDA below managed to video one in action. 

As usual with video embeds, click through if you want the full resolution and quality:

You don't have to use the slightly clunky clipping mechanism for attaching the phone, by the way. I think I'd rather have the phone (whether Android or Windows) by the side, connected by the short Type C to Type C cable.

In terms of ports, there are three USB Type C, one USB Type A, HDMI, 3.5mm audio, and a SD card slot. Which, I think, covers all bases. In theory, the NexDock 2 then also acts as a hub for your smartphone. So you can plug in USB storage, for example, and it just appears within the OS's file system, just as an internal microSD might do.

Although the Kickstarter page doesn't mention Windows 10 Mobile explicitly, I'm 99.9% sure it will work fine as a Continuum display, since this tech was pioneered by Microsoft and in all my own experiments Continuum docks and accessories also work with my Samsung Galaxy flagship and with review Huawei devices.
