Free PDF reader apps: iPDF

Parent blog entry: http://kenamored.blogspot.com/2011/03/free-pdf-reader-apps.html

PROS:

• Has capability like Safari to tap twice to either zoom in or zoom out on a column of text, a "natural" part of functionality for an iPod.
• Simple ("naive") search capability to find PDFs on the web might be useful for a casual search for a focused topic or title (e.g., "Pride and Prejudice").

CONS:

• Very basic functionality.
• Number of potential search results seems to be artificially limited.  When searching for PDFs associated with "chess", the "View More Results" button no longer appeared after I tapped it 7 times. I find it very unlikely such PDFs on the web are exhausted after 8 screens' worth of results. For more complete results, try Google's Advanced Search, specifying File Type as "Adobe Acrobat PDF (.pdf)", after which you'll have to transfer the file to some other PDF reader, like PDF Reader Lite (which I discuss here).
• Ads.

TIPS:

• To rename a file: get into the Reader, tap Menu, Rename File.  A name like CH_2009_04-06.pdf (for the April-June 2009 issue of Chess Horizons) of a series is typically more helpful than having the first few words of the PDF content showing as the title (the apparent default).  For a magazine, those words could easily be the same from issue to issue.
