because once i used pages in icloud, all my documents have been converted to the new format and i cannot longer edit them in pages '09. if i just so much as try to, i get the message they had been deleted on the icloud page.
well its the 21st century, one should think one should be able to work on the same documents on multiple devices. but unfortunately apple decided older systems are no longer to be used. like a mac pro 2.1 which can only run lion - and no more new pages
