My need to read PDF ebooks led me to just start using an iPad Mini as a reader. The app PDF Expert does a great job of trimming margins making almost every PDF perfectly readable on that size of device. (To really read every PDF without compromise you need at least a 13” screen.) As a bonus I can use the app KyBook 3 for ePub files and adjust margins and so on to make better use of the screen space. My Kindle Paperwhite doesn’t display any more text per page than a phone. Obviously an iPad Mini has drawbacks compared with an ereader in terms of battery, weight, and ability to read in sunlight. The ideal device for me is probably one of those 8” Android eink devices. Two more points—you can process PDFs for a Kindle pretty well with the k2pdfopt program. Closed-source and conmand line, but it works. Also popsockets on the back of small tablets and readers are great.
