I purchase ebooks in the adobe acrobat reader format for my computer. I am interested in finding an ereader that works the best with this same format since I like it and don't really want multiple copies of the same thing taking up space. I've tried looking into the different readers but I can't get enough information on them to make a decision. Can someone please give me some recommendations and tell me why they feel the ereader they chose would work the best for this format? Thank you.
