For making PDFs readable: from the aA menu while looking at a PDF increase the contrast to maximum and then rotate it into landscape view. Hold your Kindle sideways and now the PDFs are readable.
It's not perfect, but I have found that I'd rather read vendor documentation like this on the Kindle than on the harsh black/white of my monitor.
