I see that there is built-in support for Wacom, but I wonder if Elementary OS supports tablets for writing (there aren't many distros that I know of support this).
I installed elementary OS for my grandparents, but realized only after that they can't use the tablet input they're used to anymore.
We're Chinese, and to comfortably type in Chinese with a keyboard requires mastery of Pinyin (the Chinese alphabet), which most elderly people struggle with. Thus they need a tablet that converts their strokes to characters and input them in the system.
