2. iMessages, Siri and Photos Data in iCloud
Apple finally seems to be confident enough in iCloud to give it the responsibility to sync your all your iMessages, your personal Siri intelligence and scanned metadata in Photos app. This is a big step for Apple and it could be the end of a lot of frustrations that were caused because multiple Apple devices always seemed to be their own little islands of data. Apple is of course playing catch up here with competitors like Google but still, it’s a much welcome feature.
Now, Siri on your Mac and iPhone will work in the same way. And more importantly, your new Mac won’t spend 3 days spinning its fans because it has to reindex your entire Photos library again.
