So I'm wondering if the new macbook will be enough for me? I am planning on getting the 1.3 256 Gb version. I currently have a 2014 Macbook air i7 1.7. I am a 3rd year Finance student, and I mostly use my Macbook Air for Netflix, Youtube, Internet browsing in general. However as a Finance student I do use Excel but nothing majorly heavy with Excel. I do plan on doing some regression analysis in the near future, but nothing "heavy". Do you think I will notice any performance issues? I know its a "downgrade" but damn.... My narcism is getting the better of me in this decision.
