I tried iCloud. It was a disaster for me. I found several aspects of it that I didn't like or found not to work well. Those are all in the details which I don't feel are necessary to talk about in detail. The reason I'm writing this thread is that I've decided what's best for me is my own little local area cloud. I need to be able to sync the usual suspect data (Cal, Reminders, Notes, Contacts, etc. ) from an iPhone, iPad, mac pro and Macbook Pro. I'm sure there are folks who have built their own cloud using OS X Server. I'd be real interested in hearing people's experience. The again, maybe this is the wrong forum and I really need to post on the OS X forums.
