Apple Watch cellular, which I really like. I got a Speidel Twist-O-Flex watch band that’s even easier for daily use than the bands that come with them. I like having all the health and fitness data but it’s also just nice to not need my phone.
One example of not needing a phone I really like is having Apple Pay on it. If you’re out jogging or your phone dies or something, you can still use it to pay. It’s also nice at festivals and arenas and other places where you’re just trying to pay quickly. You don’t have to dig out your phone or wallet.
