I had a look at StarOffice on my Linux partition (dual Boot) and dropped it after about 1/2 a hour.
It has a pretty different way of managing your documents and how you select what sort of document you are working on. Didnt gel with me so I dropped it. YMMV.
I'd suggest having a read of the newsgroups and a good look at any websites detailling it before going to the trouble of downloading it.
