I also think that PalmReader is slick. It reads plain Palm .doc files
(NOT Microsoft Word .doc files, it's two different kinds of .doc's),
as well as files made specifically for PalmReader. Plain .doc files
are text only, but PalmReader documents can have text, colors,
graphics, styles, etc. You can even make your own PalmReader
documents for free with DropBook (found at the Palm website).
No one yet has mentioned the place to get the most freeware books:
look for e-books you want!
