I'm sorry to read your observations about slow typing with decent word processors.
I just ordered my Gemini, so I can only suggest hypothetically, but have you installed Wine, then an earlier version of Word, say Word 97?
Since MS has a .docx file converter, I use Word 97 in all my computers, It's bloat-free and friendly to small screens. I'm hoping to do the same with the Gemini.
I can't abide Abiword; that software is always behind the eight-ball, corrupting docs right and left.
