When the build conference keynote's over, watch the recording. I think the killer feature will be having every device you pick up be tailored to you. When you hand it to your wife, it's tailored to her... just by signing in with a Windows Live ID instead of a local user/password. Your contacts, e-mail, calendar, photos, files, apps, desktop, bookmarks, individual app settings -- it will all be there on whatever device you pick up, whether it's a tablet, a phone, a desktop PC, your work PC. Windows 8 uses Microsoft's cloud to bust through firewalls on every end to connect every device you touch.
