AbiWord 2.4.6 on the 770 works well. Word import doesn't work, but everything else does, I'm told. I will be working on a new Maemo release of AbiWord soon.

(and yes, it's unstable on the N800 because it's built for the 770, and the two are not entirely compatible. Once I have a separate build for each, things will be just peachy-keen)
