iPad Pro for the Working Photographer

I recently saw an iPad Pro while I was shopping. The size is awesome to show my work to clients but I still had a hard time justifying the cost. I currently have an iPad and basically use it to watch TV while I am working. With some research I realized I can use the iPad Pro as a retouching tablet. I have used Wacom tablets my whole life and my work depends on them. To my surprise the Apple Pencil and the iPad pro work very similarly to a Wacom Cintiq tablet by using an app called astropad. Still early, but I have found being able to walk away from my workstation and sit on the couch to retouch images has been liberating. Now if Apple could make a 30" tablet it would truly be awesome.
