Apple’s new smartwatch is bigger and better than it used to be — but it’s still a delicate flower compared with some of its competitors. The $399 Apple Watch Series 4 ($479 with cellular) is a major upgrade to the company’s wearable: It’s slimmer, lighter, faster, and has better health tracking abilities, including a unique electrocardiogram function. I got a brief wrists-on at Apple’s launch event earlier this week (where it also announced the iPhone XS/XS Max and the iPhone XR).
