I had mentioned on my Patreon page a few weeks ago that I've started using an iPad Pro at times for coloring.
Someone asked me if I thought the screen was too small. I've got a video coming this Tuesday (October 10, 2017) with my full run down & sort of a review on the iPad Pro (2017) and why it replaced my Wacom MobileStudio Pro when I'm working away from my main desktop. This image is part of the video, but I thought I'd share it here.
The iPad Pro is light enough to used in portrait or landscape mode, and when you turn it vertically, the comic page on the screen is actually about a third larger than the 16" MBP in landscape. Now you CAN turn the Wacom vertically, but I don't believe it's really designed to work that way, plus trying to hold a nearly five pound (2.25kg roughly) device vertically just isn't comfortable. Hopefully this explains why it isn't too small. :)
