Yep, it's no good just adding features to Word and Excel anymore. The future of Office is as a collaboration and communication platform. Of course, it's no accident that this version of Office will also help drive server sales. I think InfoPath is one of the most interesting products in a long time but version one seems to be missing a lot of customisation ability. It's the one to watch since it could become a new universal front-end to numerous business processes. The new version of Outlook is excellent.
