Seriously, if you have not yet signed up for a Gmail account, you need to - if for no other reason than to see what all the talk is about. My guess is that Gmail's approach could save you hours every day. You will also see the application that started this whole Web 2.0 / Web Office phenomenon. An enterprise version of Gmail would provide Microsoft and IBM with an enormous amount of competition.

Enterprise Gmail, or any other enterprise Web Office email tool, could save companies time because it does not require sorting mail into folders. It would also increase security, as web based client would also offer the latest in virus protection.

But the integration capabilities are where it becomes truly interesting. There is no reason why a Gmail UI could not also be used to post to Enterprise Blogs and Wikis.
