Hey Robert,
How well would a PDF with 5.5"x8.5" pages work on the EZ Reader?
I ask because I am writing my own pen & paper fantasy RPG and figure some players and GMs may be interested in having e-copies. Originally I was looking at the EZ Reader (actually larger version) for research but after hearing much of what has been stated so far the 6" may work well for the PDF version of the saddle-stapled physical booklet versions of my FRPG

(part of my goal was to create a product easily portable by soldiers in the field, etc). Note that using Open Office one can easily make PDFs with "half-sized" pages (5.5" x 8.5").
