Here's the thing — of you want more endurance you can get extra batteries (and with USB-C you can probably start using interchangeable standard power bricks) but if battery life is adequate you don't need to. How is this worse?

One of the things that has changed my life for the better is switching entirely to devices that can use any USB power brick or USB charger in a pinch. This includes my cameras, tablets, phones, audio gear, and so on. The only remaining outlier is laptops.
