Krita is awesome. Tablet options not so much. Many Intel based tablets are rather heavy and clunky comparatively, or have poor digitization. Touch screens aren’t the same as digitizer pen support. Some like the surface tablets are proprietary enough that you have to jump through many tech hoops just to set it up. And then there’s the cost. You can do it but its expensive in money and time. It has to be something you want to do for yourself. Because it will not make monetary or otherwise.
Android tablets are again loaded down with tech hurdles. Can they be unlocked? How hard is it? And what special hardware might you need to do it? Then you have to consider how hard is it to flash a different operating system onto it. And finally, how much of the proprietary hardware is just not going to work, and is that a deal breaker.
There is a version of Krita for Android. But the few devices I have that can launch it. The UI is unusable. Everything else works. You just have to fight the UI hard.
I got an older ARM based chrome tab for about 40 dollars. Went through the hoops to put postmarket is on it. Only the camera doesn’t work. But the 4GB of ram is the biggest bottleneck. CPU cores are fine. But just sitting idle at the desktop a little under 1/8 of the ram is already used up. Open Firefox or chrome and you are already swapping hard likely. Krita works well with the USF pen support. But the ram again is a heavy limit on document size. It’s definitely not for most people.
I desperately would love a good affordable Linux tablet platform. KDE plasma’s touch experience has been really good. Not perfect, but most of the hitches are edge enough cases in daily use. If someone would make a shell with just a full HD screen and pen support capable of using a compute module SOC. Raspberry pi or other compatible SOC. That would almost be ideal as long as they could meet a decent price point. Which is always the thing that tends to kill these concepts.
Considering the vintage of the system. USB 1 caps out around 1Mb. So its more likely than you think. 13 drives at 78.7 Kbps would easily do that. And considering each floppy should be capable of 250Kbps it’s capable of much more.
