Ok. Tried it and everything was very easy to install on the Macbook Pro & iPad Pro etc. The ExpressKey Remote works a treat and effectively means I don't need to touch the laptop for anything at all and have all the speed of the Cintiq shortcuts on the remote. Such as brush size, scrolling brush and tool selection and what ever else you programme the remote to do. I guess you don't even need a wacom tablet/cintiq to use it either, just the drivers installed. The downside is that you would have to pay £89 for the privilege if you didn't get it with your 27"Cintiq.
Seriously though, this speeds up using Astropad tremendously, feels just like using the Cintiq but on a smaller screen!
What would be useful (i don't know if it's possible though), is to be able to shut the laptop while using it, similar to what I do in the office when I work from the Cintiq and monitor. It may have to be hardwired though for that I guess. Great stuff though!
To hardwire is it just a case of using a lightening connector - HDMI / thunderbolt cable?
