Does the PDF viewer on the pocketbook 302 handle the PDF Form functions (filling out fields, drop downs etc)?
And if so, does it handle saving of that information in the reader?
I'm thinking of Soduko's and Logic Puzzles (via drop-downs or the keyboard) as I think that standard Acrobat form features (drop-downs etc) will allow those to be created there...even the "typewriter" feature is all that's really needed.
p.s., for those that know what I'm talking about, I discovered today (after years of searching) that Adobe have finally allowed Acrobat Pro 9.x (9.3 at least) to switch the flag that allows Acrobat Readers to SAVE the form entries they make in PDFs. Previous to v.9, you needed some Adobe server software which was very pricy to flip this DRM'd flag)
