Ariya sent an email to the KOffice list today passing along this link to an interview with the program lead for MS Office 12's new UI. All I can say is WOW. This is stunning stuff. A colossal change and, IMO, a great one. They have taken an incredibly complex app and eliminated all of the menu's _without_ eliminating the functionality. They've also made it so that none of the functionality is hidden.
Here's a screenshot:
Now, I haven't actually played with it, so it might come off worse in practice (perhaps the hit to screen realestate is just too much for laptop users for instance), but I have to applaud their courage.
We have to show similar courage for KDE4. No, not to eliminate our functionality, hide it or rock our users, but to develop something compelling :)
Can you imagine if we could take apps like Konqueror, KDevelop, KWord (insert-favorite-complex-KDE-app-here) and eliminate the menus while still delivering and presenting all of the functionality... the mind boggles.
