As someone who's been using LibreOffice regularly since it was made the default office suite in Ubuntu, I can attest personally to its ongoing improvement in usability, performance, and looks. As of today, LibreOffice feels smoother, faster, and prettier to me than OpenOffice ever did.

I can't wait to see what the talented LibreOffice developers decide to do once they have finished cleaning up legacy code and can focus almost exclusively on those things that impact user experience the most.

LibreOffice's usability, performance, and looks are likely to improve dramatically over the next couple of years.
