Actually it looks like they imitated some features and solutions from OS X, not just simplicity per se. For instance the dock, how the user can control the menubar (taskbar in Windows) and how you select a wireless network. By Redmond running their photocopiers ;) Windows inherits some simplicity.
I'm drawing those conclusions just from looking at the pictures. I wonder if they are starting to "get it" now.
I think it's great. When I am going to run Windows once in a while in the future, it will feel more like OS X.
