I have to read a lot of A4 documents in pdf format and would like to do this on a tablet. I have tried a Nexus7 and moving down one column and up the next is tiresome. I can view a full page reasonably well on a 10 inch tablet but I would prefer a smaller tablet for lightness and portability.
If I did use a smaller tablet I would like to view two column pdfs as single columns. It looks to me as though this is not possible using Adobe Reader. Are there any other options?
