I am little surprised about new windows user interface. It looks almost like windows mobile operating system.
I liked the bold move taken by Microsoft. I am sure there is going to be an option to have base UI look like windows 7.
Ergonomic keyboard for those big touch screens.. there is some time. :)
What would be great if Microsoft can integrate Kinect technology by using camera on the screen so rather than using those finger touch screens, we can have slight node or eye movements that will help operating system switch apps or move next/previous. It would be great in some of those apps like Internet Explorer and while reading documents.
