Tried that. FBReader just feels too small. MicroB/Tear usable but I am constantly tempted to switch to full screen. Maemo Mapper feels like I am looking at it through a keyhole.

So, what was the purpose of this experiment? Were you trying to prove that smaller screen is "still ok" or what? Because the miracle you expected has not happened: all the use cases described before in this thread felt constrained and less comfortable.
