As much as I love the iconic blue OS X desktops, the grass doesn't look that bad. It would be great if they make a new blue desktop for the hell of it anyway.
Steve announced that Apple is doing away with the what i consider to be the iconic blue desktop wallpapers that have been in OSX since the beginning. He says "nobody uses it"
I think what he meant was: "We'll stop optimizing our GUI for a (more or less) monochromatic backdrop, and take in to account that many people use a digital photograph as a desktop background."
