Melitabel, get coolreader for reading on the LCD side
http://sourceforge.net/projects/cren...s/CoolReader3/ it accepts epub, PDF, text and several other formats.
Epub and PDF can be read on the e-ink side.
Calibre installed on your PC will convert all non DRM books to either of those formats and transfer them to your PE for you.
I have Kindle for win installed in windows in a VM which I use for downloading books which then get converted for use on my EE, likewise with the B&N books.
As you know not all apps work with the PE or EE, sometimes an older version will work whereas a newer one won't and vice versa. At the moment I know Coolreader 3.0.45-11 works on my EE so it should work on your PE.
