Looks like some pretty nice improvements, particularly in regards to window management. From the video, it sounds like they're adding persistent grid layouts, with apps able to be assigned to specific tiles in the grid, and Windows remembers and restores those positions when you restart apps or switch monitor layouts (e.g. when connecting a laptop to a docking station). Looks like they've also expanded the multi-desktop feature to integrate nicely with these new persistent grid layouts, with labeled desktops for particular tasks. The new native support for Android apps also seems like it could be really useful, depending on how well-integrated it is with the rest of the OS.
