I am using mountain lion right now and just tried to save a document in pages but there was no icloud option, i had to upload it using the web option and there is some iwork beta thing u can use the web as well for sharing... Still not incoropating the icloud into the desktop versions, i did notice in text edit there is a direct icloud save feature, however, i dont know of a textedit app available on an iOs device... And no, im not talking about notes, i know that usies an icloud like function already and that works well too, but its pages and the other iwork apps we would like to work with the icloud feature they say is available...anyways, i am just using a developer preview of mountain lion so maybe in the final release they will incorpoate that feature, however, i just dont see it happening... also, i think its more of a PAGES feature that needs to be added, not mountain lion... we shall see in the next coming days/months...
