I want to try one of these and I'm a chronic early-adopter, but some support for a smartwatch (I feel naked without my MS Band nowadays), and 4G LTE compatibility in the USA are part of an MVP for me to try out a phone nowadays. It's my understanding that Ubuntu Touch and the devices it is currently running on do not offer that. Anybody know of a roadmap/timeline for when Ubuntu Touch will be adding these features?
