The glitzy look of the recent IBM Lotus Symphony release got my attention pretty quickly. While trying it out on a couple of tasks I rather rapidly started hitting various bugs. That said, I think the OpenOffice folks could take some hints in usability from this project.
The biggest issue that I ran into was with Bold, or Heading text not showing up on a page. Technically the the word processor thinks that the text is there because I can move my cursor through it, however it just shows up as white. Closing and re-opening the document will show the text for a few moments, but it will disappear again pretty quickly.
This is a deal breaker for me. So I won't be recommending it to anyone for the time being. Too bad really.
