I totally agree regarding iCloud. At first, I was a skeptic of The Cloud back in early 2012. Back then, it wasn't even Apple that was hyping The Cloud. It was those other companies like Google and Microsoft throwing around that term as if they invented the concept first.
But now that I experienced first-hand how iCloud allows my (new) iMac to easily synch and seamlessly integrate with my iOS devices, I'm sold on the concept. Is it perfect? Of course not. iCloud has some known glitches that need to be worked out (a good example are the duplicate Notes entries, which I have already experienced). But so far, none of the iCloud problems I have seen or witnessed are deal-breakers. Regardless, I'm sold on the concept. It really does make things easier for us Mac users.
