I'm looking to replace my 2015 15" MacBook Pro and one of the primary reasons was due to travel. For the next few yearsI will be working on the commute (train) for around 10 hour per week and this is where the 13" appealed to me. However, the high end 13" only comes with 8GB ram and to upgrade puts it at £2,200. For comparison the 15" is £2,400 for system wide improvements, except SSD is only 256GB, plus I'm not sure I want 15". I'm going to be running windows 10 daily via bootcamp and using 3D modelling software and Adobe suite. I also have a work Windows laptop (made for gaming) which is very capable but far too big for the train. Question is, do I accept the small price difference knowing the performance difference is pretty big and go for a 13" or go for the 15" and potentially struggle for storage?
