What the world needs now ... another webmail system?

Zenbe has taken a different approach to innovation than other companies such as Xobni or Xoopit who have provided add-ons or complementary services to popular email clients. Zenbe sports what beta users say is "a beautiful interface."  It has tabbed viewing and organization of emails and file types through "ZenPages" and supports widgets for YouTube, Flickr, Google Chat/Maps. It tries to take email and make it a socially collaborative tool. Personally, I'd rather see someone introduce a product that improves Microsoft Outlook's performance, that's a dog that will hunt. It's difficult for users the change email systems and some set up auto forwarding of multiple mailboxes and collect them in one system. Most users have at least 3 email accounts - work/corporate, webmail and an ISP/POP email client. The webmail choice is always up for grabs but with ever increasing storage from Yahoo or Google, it doesn't make sense to move. Besides, all these companies have access to the same development tools and technologies so new UI features from startups can easily be added.
