If you want to complicate your life (though I call it fun) you could always install a mac emulator and use one of the many word processors and spreadsheets available on the old 68000 apples.
They generally run slightly faster than a mac of the same amiga processor spec, although graphics will be slower on AGA than a real Mac ( though faster than workbench in the same colour depth, which is annoying).
I used to use photoshop on my amiga, back when I could not afford a mac for my graphic design course.
