Really struggling folks - based on my usage (office, statistical analysis, advanced excel, no video editing or gaming) , I am confident that 2016 or 17 MacBook Pro without touch bar (13 inch) will be sufficient. But the 2017 with 256gb SSD (I need 256) is costing $300 more when compared with refurbished 2016 model. IS 2017 worth paying extra? Besides kaby lake being 10% faster, don't see any other changes - could be wrong though. Would love to hear your perspective and experiences.
