Hello all. I'm looking to buy an e reader primarily because I need to access books that I otherwise cannot. And I also think that the email version of  most books is cheaper.
  However, I realised that, kindle paper white (which I almost decided to buy) doesn't have a pdf reader and I'm in a fix.
  Can someone enlighten me please, not just on this aspect, but all the pros and cons, so that I can make a smart and informed purchase.
  Thanks in advance:)
