Today is the day that Apple will release the new iOS 11 and watchOS 4. Apple typically releases iOS updates between 9am and 10am Pacific, so I typically check for the update around lunchtime here in New Orleans (Central Time Zone). This year, I won't be trying to update within the first hour — not only because that caused problems last year, but also because I happen to be in trial today. But I do look forward to updating both my iPad and my iPhone tonight.
iOS 11 is a major update for the iPad. With the Files app, the new Dock, multitasking and drag-and-drop, you will be able to get much more work done, much more efficiently. On the iPhone, I'm looking forward to the improvements to Live Photos, the new Siri, and the new Control Center design seems much more useful.
On the Apple Watch, there are some nice improvements to the Activity and Workout apps, and the Siri watch face could make the Apple Watch an even better assistant.
