Further to the previous post, I just installed the OpenOffice 1.1beta release. From first impressions, though not on the scale of Ximian’s vision, the UI is nicer, and the options seem to be more logically organised.
A tip I’d give is to use Font Replacement in the options dialog. Replace Andale Sans UI with whatever font you want OO to use as its interface font. I chose Arial, but you may choose whatever takes your fancy =)
