Apple released a new TV ad that explains the content syncing of the iCloud in 30 seconds and without words.
Why use the Apple iCloud? The new Apple TV Ad makes the point in 30 seconds and without words. Enable iCloud and your are ready to go. Take a photo on your iPhone and it appears in your iPhoto on your iMac at home. Create a contact or calendar entry and all your devices are synced with the new information. It all looks so easy and natural.
In reality I find iCloud is indeed very easy to use, but is not always working smoothly. I often need to download stuff on request as its not there on all devices automatically. I also seen many cases where the sync is not instant at all. Watch the iCloud TV ad below.
I did not have the time to figure out why this is happening. Speaking of issues. I have seen now several times hours of iMessage delays. What is up with that? If an iMessage is not delivered instantly it is not replacing SMS.
