The ability to adjust the degree of clarification / fat content: Many programs or books/pictures have extra black dots near lines, caused by scanning artifacts (for example). You can manually adjust, at any convenient time, remove these dots, enhance the rendering of the font. This is also a minus - it is not automatically applied, the last configured one is saved. You have to adjust for each book individually. The general impression is that the pdf text looks better on the iPad. But in general, quite tolerable. :)
