Scrolling through the
300+ New Features page at Apple I noticed a mention of ODF under the UNIX heading. Curious, I found an ODT file, right-clicked and there it was: under NeoOffice, TextEdit.app sat there claiming it knew how to open my document.
Both opening and saving works, the fidelity is about what I'd expect. But there's more: the new QuickLook feature
also works with ODT files (see the screenshot of part of the ODF spec itself). Just find a file in the Finder and press space to look inside.
