That is only true for the viewer version of Documets To Go that is preinstalled on the N900. The premium version of Documents To Go can edit Word and Excel files. I bought that version some time ago and am quite satisfied with the performance. The upgrade from the viewer version only cost $9.99, no idea if that offer is still valid.
