Three reasons why you shouldn't immediately upgrade to iOS 10

The new iPhone and iPad software lands with a number of new features, including a new Home hub for smart devices, improved Siri functionality, facial recognition for a revamped Photos, and a redesigned News and Music apps. Apple also enters the artificial intelligence mix by collecting data to be more helpful, such as picking out calendar events and emojis. The public preview is open for download. But before you install iOS 10, there are a few points to consider first. Any pre-release software will be riddled with bugs and issues some of which won't be fixed until its final, official debut -- sometimes even later than that.
