If ECO Reader owners don't want the option for using XPDF, we can remove it with a firmware update.
Actually have XPDF is important as it can handle eBooks that are made from images better than Adobe can. But perhaps there is a better way to offer this choice than having to open a book and select it from the openbook menu. There should be a choice in tools/user preferences for this and other items.
