I owned the original watch and while I enjoyed it for a month or so but the novelty wore off rather quickly. I sold it and never looked back until last week when series 3 began to peak my interest. Overall I’m loving it and appreciate the refinements that Apple has made: the user experience is much more fluid now and everything is intuitive and runs much faster than the original. I installed watch OS 4.1 beta last night and everything continues to run as smooth as 4.0 with the welcome addition of music streaming. Overall no complaints, below are situations I’ve found the LTE of benefit: Long run - music streaming was flawless Gym - being able to ditch my phone Kids - I have small kids and love being able to leave the phone behind and be fully present with them while being able to stay connected to messages, phone if necessary.
