You just need an Android tablet with EPD display and a decent word processor.

If you do not want full formatting - so, you are contented with typewriter like rendering -, there must be abundance of software application. If you want proper typographical paragraph formatting, with e.g. full text justification and spacing etc., there are a few usable applications. (As written in anther post, in the end, to have an application with all the features I wanted, I wrote it directly.)
