@jamesley I use my iPad Pro and love it. I definitely agree that drawing on the tablet while looking at it is important.
I used it in combination with my MacBook Pro and Astropad App (the one-time paid version). I really liked it. I had to upgrade to a PC and have not used it yet with that but had gotten a couple of apps to try with it. I see that Astropad is mayking a windows version for their Luna companion App so I am holding out for that.
In the meantime: I use my iPad Pro everyday for journaling and I also use it for 2D art on Afinity Designer. I use that app for a lot of my texture maps and just save them to a cloud server that I link Blender up to and then just ‘Reload’ the images when I make the changes on my iPad. I try to make use of what I already love using. I recommend to go with what you are comfortable with.
