Thanks - thought that would be the case. Will have to have a play with one and see how good it feels. Tried the tab S3 today and it did seem pretty good with the Autodesk sketch app and the screen was incredible but like you say the sw support on apple is bound to be better.
Affinity Photo, Procreate, using Astropad to mirror Photoshop on your Mac - there's all sorts. Also there's obviously the ProMotion to consider as while this won't change much in regards to using the pen itself, I'd assume it would make panning/rotating/moving stuff look and feel smoother.
