On your finger, or in your pocket
A pocket device has room for a bigger screen and more to do on it. A ring is always on you, and a glance and a buzz are enough for most small things; the rest comes at your ear. Which suits you depends on how often you want to take something out of your pocket. More on the idea in a phone-free assistant.
