I've had a MacBook Pro since 2013, but it's on its last legs. I am in law school, so I don't do anything too intensive. I mostly just work with large documents, and often divide my screen so that I have notes on one side and docuements on the other. I'm debating between the 15" Air with an additional 8GB of ram and the 16" Pro. Both are withn my budget, but i would rather not spend uncessary moeny. What are your thoughts?
