I don't know who doesn't have MS Office anymore, but if you don' t or you need to get rid of it but have to stay compatible with your colleagues, LO is the way to go.
It's actually got some features that are better than Office, and it's become a lot more polished in recent releases. I still don't like the overall color tone of the interface - there's something a little amateur like about it - but it performs fantastically.
I dontated $10 to them the other day because I think it's awesome that there are people out there providing free s/w for others. If you don't have or can't afford MS, you can get something that's just as good and in some ways better for free with LO.
