The Lenovo Yoga 6 works surprisingly well. I got it to replace a surface book for my daughter and wasn’t really sure what parts of the hardware would be supported, but literally everything I tested works (the only thing I haven’t tried is the fingerprint reader) and the included stylus is amazing in krita as well as just generally. The tablet mode works well, and tent mode is more convenient when it’s on a desk (screen rotation requires the iio-sensor-proxy package). Battery life is decent; it gets around 6-7 hours with moderate use. I’d recommend using it with KDE.
Termux is awesome! I use it for a bunch of things:
I’ve been using gimp’s 3.x branch since 2016 or so (after getting a hidpi display) and gimp itself since the early 2000s, both for personal stuff and for work. I’m typically editing existing photos and images to clean them up, apply effects, make new clean images from pieces of existing ones, etc, and for my uses it’s great. Also, having been using it for so long, I actually really prefer the ux to Photoshop (especially since they added an option to use it in single window mode).
I’ve seen videos showing some of the features it’s missing for certain types of things though, and while there are hacky scripted ways to emulate them, you might find it lacking if you’re expecting those particular features.
I’d recommend looking up tutorials on YouTube for things you frequently do and see how much work it is and what the final product looks like. You could up the playback speed to save time since you won’t be following along with gimp yourself.
