Ertain@zeppy5d Sorry, there's very little hardware that *might* fit these specs. A tablet computer may be your best bet. This is because I don't know of any tablets that can run Linux well. Maybe @davidrevoy knows of one?
David Revoy@Ertain @zeppy5d Unfortunately, there is not. iPad are still 10 years ahead in terms of hardware and software fine tuning together in this area. Some laptop with stylus (active stylus, with battery) like some Yoga thinkpad are compatible with the Wacom Bamboo Stylus, that's what I have: https://www.davidrevoy.com/article976/lenovo-yoga-370-on-gnu-linux-technical-companion-article , I also bought a Ms Surfaces 3 Pro but the implementation of their stylus (n-trig tech) is bad. Unusable for painting. And Krita in a context of tablet without keyboard is also meh. 😔

Yes and no.
#Apple's #iPad makes it easy to test, build and sell #CCSS [commercial closed-source software] at a premium.
- I mean, I'm happy with my #X230Tablet but I do acknowledge this is an old device and it's rather the exception than norm...
Simply because #Wacom makes good passive stylus and pen-capable touchscreens.
- So OFC companies that have the money and resources to build premium #apps will target the premium customers who by virtue ob being able to splash 4 digits on a tablet brand-new will be proven more able to pay for their software.
That's why #Autodesk won't even sell people a #Linux license for #Maya (or any of their other tools) unless one has proof of ownership of a certified workstation (i.e. HP Z-series) with a #RHEL [#RedHat] #Workstation #subscription active to begin with.
- And yes they will run the machine's serial # to check if it's ordered with parts that fit their system requirements from the factory and will demand the same for RHEL. I've been there and had to do that before they even consider offering one a subscription!
Compare that to like #AffinityDesigner on #iOS (or rather "#iPadOS") and the fact that basically all iPad users are expected to have an Apple account and credit card linked to it for the #AppStore and it's no wounder the developers of creative apps will focus on that.
The only exception are #FLOSS #apps that are native to Linux and/or got started on other #Unix Systems [#blender started out on #IRIX as CCSS] and serve #macOS & #Windows as 2nd & 3rd tier platforms [i.e. #darktable oftentimes had no Windows builds because none of the devs had or wanted a Windows machine to test on!]
CB@kkarhan @davidrevoy @Ertain @zeppy5d
Except with Affinity i can buy a license for their entire suite of products for one low cost and use it across Windows MacOS and iPad as well.
