Office Mobile has been updated to 6.1 - it's a free upgrade for anybody who already has Office on their Windows Mobile device (that almost surely means you). The update (finally) adds support for Office 2007 file formats, catching up to what DocsToGo managed to do quite awhile ago. If you don't have Office Mobile on your device, it's $49 to purchase.
Oh, and the release of Office 6.1 is for really real now, not an accidental release like the last time we saw it.
