I have the onyx boox nova air c which has a stylus and color e ink screen. I don't really use it for drawing though. The colors are pretty limited (think a faded old timey comic book). But the stylus response is good. I haven't tried drawing apps but I can run pretty much any android app on it.

I mostly use it for reading manga/webcomics, typing books, and reading. I've got it loaded up with a some Latin dictionaries so I can use it for language learning. The nova air c is an older model so maybe the color screen is better on the new ones lol.

The color is nice, but for serious artists I can't imagine the nova air c is sufficient.
