I've used LibreOffice ever since the split when Oracle confused the OO picture. I'll stay with it on Linux at least for as long as the Apache license keeps OO taking advantage of code available from Libre.
Unfortunately, some collaborative projects I'm in requre accurate presentation of marked edits from multiple people, and MS Word still sets the standard for that. Libre is better than it used to be, but it still misses things that can totally confuse where a document stands. So I start a Win7 VM on Linux just to have Word's editing mark-up capabilities when I need it. Plus, the mark-up editing Libre does have is a nuisance to turn on.
This is a good article, HTG - it drills right down to the essentials, the way you generally do. I hadn't understood that OO was limited by its current Apache license before; it explains quite a lot I'd found puzzling about the relatively more advanced capabilities of Libre.
Now I guess I'm gonna try Kingsoft Office - I hadn't even heard of that before, so thanks also to ReadandShare for the pointer. There are other fast-loading, reasonably capable word processors (Abiword comes to mind) but Word compatibility is important to me and to a lot of others. It's just one of those facts of life, I guess.
