One Logitech unifying receiver works for both the MX Master2 and K780
That will need another usb port. Some devices only have one usb port . Better buy keyboard with trackpad or mouse with it . Even Logitech makes many of them .
will this work on the xbox one x for typing in information like passwords ? since the app on the ios does not let you use your ipad as a keyboard which is a joke really
I tried everything over the years. Simple USB switcher is fine if devices have a USB port (of any variety with the right adapter).
I have this and switch between a mac and an iPhone and an iPad seamlessly, it works very well. Worth the money if you want the convenience. The biggest joy is the slot at the back that you balance your phone in - super easy to use. If you think it's expensive because you are comparing it to "just a keyboard" you are missing the point of what this does - it's 3 keyboards in the space of one. I got mine cheap in the Maplin sell off but this is a good price. I did think it was expensive before I had it but now i'm using it I think it's good value if you need these functions.
