First, we hear from Jim Hamm. "If you've upgraded to iOS 8 or Yosemite you're probably aware you've now got iCloud Drive available. If you, like me, may be wondering what this is all about, here and here are two articles from the TidBITS Newsletter you may want to read."
Jim winds up, for now, saying, "In theory, I use iCloud -- since I've uploaded 'stuff' to it -- but in practice I don't really use it as I find Dropbox (which I use frequently) more convenient. In fact, I've never even checked to see what might actually be in my iCloud account. Now I've got iCloud Drive to wonder about and figure out how it fits -- if it does -- with iCloud."
