securitas writes "The first users of Microsoft's Office 2003 are weighing in and the response is mixed. The new Outlook has received a favorable response, but the mantra seems to be there's little reason to upgrade unless you absolutely need the new features. Meanwhile, Bill Gates dismissed the open source competition. One of the new features - self-destructing documents - seems to have caused some confusion, because 'Microsoft says the new feature is not designed to remove all traces of a file' and MS spokesman Mike Pryke-Smith says, 'The message will still be in various places', so emails will not cleanly self-destruct. A related issue is the permissions technology called Information Rights Management, which may shut out Mac users. PC World has a detailed review of Office 2003 which sums things up well."
