I find reading PDF books fine to read because most are about 9" including the margins. Good PDF reader can easily autocrop the margins off so you don't have to pan-zoom the pages. When reading pdf gets a bit cumbersome is when the PDFs are letter/A4 or bigger. At this point you can use reflow, and which works great, so long as you don't have pictures or graphs.
As for a reader I recommend both RepliGo and ezPDF you can have both for around $5. Each one of these have some advantage over the other and both are excellent readers.
Thanks for that! I guess this is partially about personal preference and he'll just have to test it out to see what he's comfortable with it. In his field, nearly all the journal articles are text only, but there is the occasional table and sometimes the journal format is two columns. And I've noted an additional vote for ezPDF
Like Harry, I'm also wondering which orientation you use.
