For anyone interested in what the next version of Word should look like in a year or so's time:

It's interesting to see that Microsoft is moving away from File|Edit|View|Insert etc user interface, having a "ribbon" and Write|Insert|Page Layout|References|Review| etc instead. Given File|Edit|View|Insert has been copied by pretty much every Windows developer, will other developers copy this new approach? If they have over 100 functions in their application, then they could well do so.
