One of my largest complaints against OpenOffice is their choice of target for development. Aiming for Microsoft Office look and feel is like going for a swim and aiming for an open sewer drain.
With Lotus Symphony, I get the feeling that IBM has junked the idea of following the Microsoft Office format and going for a much better minimum standard. The program reminds me a lot of WordPerfect 9. Personally, I think OpenOffice and Sun should think long and hard about targeting Microsoft products a standard for how their program should behave.
