I don’t see anything that makes it less optimized for desktop. Yes, the styling joins the family look of the iPad, but this doesn’t mean that it becomes a focus on touch. Mac is still very committed to a mouse/trackpad/keyboard interaction model. I think that 11 looks good and brings in some useful features from iPad and lends some good UI elements like sidebars to the iPad. It’s a good marriage but not a merging.
