Nothing more to say then to watch this video at Channel9 : http://channel9.msdn.com/posts/PDCNews/First-Look-Office-14-for-Web/ ! Looks pretty impressive if you ask me.. real online collaboration, the ability to work on a document at the same time as someone else does. Seeing the changes immediately while working on the document.

Btw.. notice that Antoine Leblond says “.. so that customers can actually run these on their SharePoint servers within their enterprise..” ;)
