Getting better, lots of functionality... but for me still not a serious alternative to MS-Office. Main criticisms:

1. Spreadsheet and Presentation are very slow. For example, it takes forever to load a complex spreadsheet with multiple sheets, graphs and calculations. This is not acceptable, whatever the reason is, and in particular not for software that otherwise offers similar functionality as Excel.

2. Still no support for plugins like EndNote, used by many scientific writers. There is a workaraound but which is not acceptable if I need share documents with coauthors that use MS Office with EndNote.

3. Conversion of Excel Spreadsheets with graphs is not satisfactory. Again, If NeoOffice is intended to be an alternative to MS Office, problems like this are not acceptable, unless it clearly outperforms MS Office otherwise.

Obviously, this software is written by highly motovated people that are idealistic enough not to ask money for it. I have already donated, and I would be among the first to spend more money for this software once these drawbacks are corrected. I think that it's great to have free software, however, if productivity suffers, it might not be the best alternative.
