This. In the coming years it will be increasingly convenient and perhaps mandatory to have your data on iCloud - if you want to backup, restore or find your devices. The latest iCloud upgrade allows for 1TB of data - it's easy to imagine having your entire laptop, phone, ipad up there in the near future. So physically preventing access to a single device is not nearly as important as protecting your entire digital life in the cloud. This announcement by Apple is a good sign, but it feels like the real battle for privacy from govt snooping will be in the cloud.
