I have typically avoided iCloud for in the past for 2 reasons: 1) Not sure I can ever do a mass delete. 2) Not 100% how the syncing across devices work. So if I enable iCloud on my iPad, iPhone and my Mac, and lets say I have safari bookmarks on all 3 devices. How can I control what bookmarks show up on what device? It just gets confusing to me because if I have a bookmark on my Mac, and not on the iPhone & iPad and do not want it transfer is that a possibility or is it all or nothing? Then that asks the question if I want my iPhone bookmarks on the Mac and not the iPad is that a possibility? Or lets say I do not want the iPhone bookmarks to sync with any device....? Appreciate any feedback as I am curious as to how it truly works and what all I have control over. Second thing is lets say one day I decide to sell all my apple devices and leave apple and go for a Samsung device. Lets say I want to delete everything in my iCloud account, which I know Apple can delete your account if you call in but how can I ensure all my pictures/documents/contacts are deleted on my own?
