Here is my set up of Onyx Max 2 Pro using it as a portable laptop. My boyfriend made the attachment/cradle using Lego pieces and it slots onto the Logitech Bluetooth Keyboard (K480). I have a dial on the keyboard which changes the channel. So I can switch between 3 devices. You can get a bigger keyboard but its a bit on the heavy side. I also use a desk lamp for ambient light. The photos are taken without the lamp. There is a cable running to power the usb light, but I also have a battery operated light if I am on the move. Not sure if I can upload the photos here but here is a link:
