At Dell World, Steve Ballmer gave attendees a look at some interesting changes in Windows 8 and Windows 8 server.

--A lock screen that settles over the absent user's machine with a peaceful mountain view. Despite the lock, incoming email prompts an update on the number of unopened messages at a small envelope symbol. Social network updates or other active applications can post counts next to their symbols on the lock screen. When you come back to your desk, you can quickly tell how much has been going on in your absence.
