The fact that you can change font sizes easily means the iPad effectively replaces reading glasses. I disagree. Reading glasses are close to the eye and magnify without sacrificing the amount of text to viewable surface area. People who need to significantly increase the font size (i.e. the same people who would use reading glasses) are going be constantly interacting with the iPad to tell it to pan/scroll the viewable (magnified) surface around so that they can see everything. Pagination is only a partial workaround (still have to interact, just deal with the large increase in page turns) and only makes sense with text-type data (e.g. pictures lend themselves to panning, not paging).
