This whole PDF discussion thing is getting pretty old. Adobe designed PDFs to be printed, not read on E Ink readers. They designed PDFs over 20 years ago for the purpose of being able to exchange secured documents digitally without worrying about unauthorized editing of those documents. For example, a lawyer could send a contract to a client via email. PDFs were never designed for our viewing pleasure!!! True, Adobe has tried to update PDF over the years, but it is still THE WORST form of document for reading on an electronic device.
