Not sure if this has been answered elsewhere, couldn't find anything here. I have an iPhone running iOS 8, an iMac I am about to install Yosemite on, a 2008 Macbook stuck with Lion and an iPad 1 with iOS 5. Does anyone know what will happen to those devices not supporting iCloud Drive, but the old "Documents & Data" iCloud functionality. Will it entirely stop working on them? I'd like to know before I flip that switch. Apple has a support article, but does not mention what happens to such devices, just that they won't sync with iOS 8/Yosemite and as expected it advises to upgrade to latest OS.
