Longhorn Aero: Visualization on the MS desktop?

Juan C. Dursteler writes in InfoVis about Aero, a user experience component of Microsoft's forthcoming OS codenamed Longhorn. He reacts to comments made by Will Poole, Vice-president of Microsoft�s Windows Platform Groups, about the goals of Longhorn regarding the user interface:

The concept that Poole proposes is to create a technology favouring the so called "Life immersion", of which Longhorn appears to be the exponent. In his own words the goal is to "embrace the human factors like we've never done before, to really understand how to make that emotional connection to our customers to address all of the product requirements, making it just work, making it something that you can invite and live with every day in new and profound ways from a technological perspective to deliver that immersive experience".

Most of the screenshots show a UI for the desktop full of photographic images/effects, but a key innovation with Aero would be giving users access to their computer data using visualization without as much reliance on the folder and file desktop metaphor. As Dursteler oberves, however, the destkop metaphor will NOT change much. The comments below seem right on to me.

It would be a pity if Microsoft misses this opportunity to offer real information visualisation to the users instead of simply offering special effects. ... The promise of Information Visualisation is to make us more productive, simplifying our life in terms of knowledge acquisition. It has nothing to do with stunning the user with visual fireworks.
