For Maemo I lowered the font settings by going into Menu->Tools->Settings.. 10 or 12 are more legible.

For Debian pretty much all of the default terminal's are pretty small and easier to read.

Isn't much we can do about the resolution yet.. until one of us put all our attention into the "virtual" desktop that was being mentioned in Easy Debian's arena.

I also find for advanced and long sessions either a USB keyboard (with adapter) or a BT keyboard is much preferred over the default on-screen or N810 hardware keyboard.
