A lot of people have mentioned that once people upgrade to iCloud Drive, documents on other devices are not available until they are upgraded to iOS 8/Yosemite. Since it's quite possible Yosemite won't be released until October (As per Mavericks), do you think it's possible that they'll disable iCloud Drive until then so that people don't loose access to documents on the Mac. This would be in a similar fashion to what they did with iCloud Keychain last year. It was in all the iOS 7 beta's and was then removed from the GM until iOS 7.0.3 which added it back in along with numerous other fixes. What do you think? I personally think it would be a good idea. Many 'juggles' would simply click 'ok' to upgrading to iCloud drive and could be left in a situation where they loose access to documents for potentially over a month. Do you think Apple will do it?
