I guess it depends on your needs and expectations.  Another person
responded to this note with a glowing recommendation.  We appreciate
the kudos, but we also wonder if AbiWord is truly deserving of such
high praise.  Yet.  :-)
AbiWord is still missing some very important features.  It's hard to
imagine living without those features in heavy usage.
Personally, I use AbiWord for almost all of my word processing needs.
But then, I force myself to do so in the hope that "dogfooding" will
benefit the project.
As for stability: AbiWord doesn't crash very often.  I did experience
a crash a couple of days ago, much to my surprise.  I've written 20
page documents, and I've had 3 hour editing sessions, with no
problems.  I'll confess that I wished for tables and outline mode
quite a few times during those 3 hours, but at least the app didn't
crash.  :-)
