"Both Windows Vista and Office are slated for release to big businesses on Nov. 30. Microsoft has issued near-final test releases of Vista, but has not yet completed the final, or "gold," code for the new operating system.
"As for Office 2007, the upcoming release sports some major changes from Office 2003, including new file formats and a radically revised user interface. In addition to those and other changes that have been known for months, Microsoft noted that it has also added a feature to Outlook to make it easier to send text messages to cell phones."
