I like AbiWord, use it some of the time. Trouble with a lot of the MS Office alternatives is compatibility. No matter how hard they try, compatibility is never 100 percent, at least in my experience. So whenever I think I have to share the doc with someone else I relent and use Word or Excel. But I'd rather not have to.
AbiWord does seem nice and lean. I also use Mariner Calc whenever I can.
Andrew, what happened with the graphic you mentioned?
