- Built in support for the online services from the ground up. From the filesystem to the drivers the system should be built around the idea that it can be updated easily from the web and kept up to date. - Ideas like DropBox and Backup services aren't a 3rd party feature/add-on they are core to online nature of the OS. - Perhaps a new way to manage files & folders. I can't believe we still use filename.ext. iOS has some interesting things here.
