I have seen today that this model has excellent battery time! I have spent close to 6 hours on it today and granted i have used primarily Safari, Skype and Outlook with 70% screen brightness. It is now around midnight, I have 70% left and according Activity Monitor the battery should go on another 9 hours! Might be a little optimistic but I have to say getting more than 10 hours doing light work should not be a problem given I have 70% left after 6 hours! Besides a concern on the fans and if they kick in as they should so far I am impressed with the 2017, including the keyboard that I like although I feel t is a bit too loud. Btw I am a touch typist. Btw how does this compare to the 13" with touch bar?
