title_body: best e-reader for pdfs I've read that kindle can be dodgy when trying to download files that were NOT purchased from Amazon?   I have downloaded thousands of pdf books
upvoted_answer: The built-in Kindle pdf reading app is very limited and not suitable for academic papers or text books, because it doesn't have an smart reflow option. 
  
  If you're on a budget and like the Amazon ecosystem, you could buy an older model, jail-break it and install the free KOReader app, which offers better PDF display options. (Note that this will work only with the first generation Kindle Paperwhite model and other older Kindle models.)
  
  There are some large screen eInk readers suitable for reading .pdf files, however, they tend to be more expensive than more powerful tablets with same screen size.
  
  IMHO, the best e-readers for .pdf files are tablets with a screen size of at least 10".
