Def thinking about this.
1) Photoshop for iPad just dropped Monday, but right now the word is that its garbage; it will take a couple of more updates before it can run like a third of what it does on the desktop. I want to start doing more art stuff on my iPad, so this would help...
2) I'm also trying to end up not paying for like 20 different monthly "subscriptions"(via apps & streaming) so this sounds good. I'm already committing to paying the subscription on CSP(though it's less than $5) and from what I've heard about Affinity Photo, you can use PS brushes with this program...Photoshop for iPad is gonna be anywhere from $10(the Photography plan with Lightroom) to $20(PS by itself) per month.
