The Kindle also writes the title and author at the top of the screen, and in this case there is no way to remove it (see
Font Sizes). The iLiad does not, even though it has more screen space, see
Mobipocket Font Switcher and similarly for
FBReader on the iLiad. FBReader has a full screen mode (nothing but text as close to the screen edge as you like), which I use on other devices but it does not work on the iLiad (you can enter full screen mode but can't get out again).
