I don't think that Sandbox should be the default theme. But I do think that Sandbox or another similar theme should come with WordPress instead of Classic to give designers a basic framework to start from.

And Kubrick should certainly be retired! The backend of WordPress has had two major design overhauls in the year, and the frontend hasn't changed a bit.

WordPress' biggest strength is its usability, my friends and clients all take to it with little to no instruction.

The design and functionality of WordPress.org, all the related sites, and the backend of WordPress itself are all fresh and inviting.

I think that WordPress needs a new default theme that is the equal of 2.7's backend. Otherwise WordPress is like a rusted out old jalopy with a brand new engine and leather interior...
