Again, thanks for the answers. From what I read after extensive googling as well as on this forum, finding a PDF reader for publications and other A4-sized documents seems to be a common concern.
Just for a good comparison (and future reference for other searchers), would it be possible for some of you to post a picture of your device displaying a PDF, i.e.
this one? My research is not related but I thought this might be educative and entertaining
Cheers!
