After ~30 years of Photoshop, I now use Acorn for things where pixel-perfect editing matters and Affinity for everything else. I miss absolutely nothing.

I did an insane amount of pixel-perfect editing in Acorn 1.0 free trial when I was a kid in 2007, always with the shareware banner blocking part of the canvas

Acorn is one of the very, very few remaining pieces of software where the update notification popping up makes me go "Oh nice, what's this then?" instead of filling me with existential dread.

I hardly do anything graphics-related these days, but I still buy each and every new full version, just because it has become so damn rare to see good software that isn't paternalistic to outright adversarial towards its own users.
