How can I access preview documents saved to iCloud from 10.8 on an iPad? As of OS X Mountain Lion (10.8) one can move Preview documents to iCloud, how do I access these documents from my iPad?
You unfortunately can't, there is no related application for iOS right now. Whether this is an oversight in Preview (which shouldn't be able to save into iCloud in the first place) or a hint for things to come with iOS 6 is unclear right now.
