good points, but web 2.0 doesn't have to be useless or necessarily in the largest font sizes.... if you look at the CakePHP layout (http://www.cakephp.org/) except for the font size it seems to have more info above the fold than the old theme?

I mean, if there's no alternative available, usability seems to come first, but if the design doesn't look catchy, people might dismiss Ubercart as an older system like osCommerce and pass on trying it. All I am saying is that ideally a good marketing image should go hand in hand with good usability, but in case they don't, they should be handled like trade-offs. That means balanced, not one for the other.

But Pixture is good and with some more flashiness to it it should work.

PS: One more good web 2.0 theme - Drupal.org itself.
