Open Office is good but like MS Office I find to be too bloated for my needs. I personally use Abiword, and even then I’m more likely to use Google Documents, but I don’t do very much. I like Abiword because it’s fresh and lightweight, and Google Docs because it lets me save into multiple formats, edit anywhere with an internet connection, and allows me to share documents and such. But both lack the multitude of features that OO or MS Office can provide sadly, but then if they did have all those features they wouldn’t be so lightweight would they? Open Office is a very good alternative to Word, and although integration between the two via document formats is bettering on the OO side (opening and saving .doc files accurately) MS aren’t making it any easier, but that’s the same with all non-MS products :)
