This is a stunning theme. Truly gorgeous. I'm intrigued by the use of backbone.js to add to its "application"-type feel. I'd love to have a copy that I can tear down and dig into how it all really works. Theme developers could learn a lot by dissecting innovative themes like this.

+1 on seeing a business-style theme from Theme Foundry. All of their existing themes are extremely creative, and it would be awesome to see them put a new spin on a theme for small businesses.
