HI I am torn between 3 laptops the macbook pro 13 inch the razer blade 14 2015 and the macbook pro 15 inch. I am primarly going to use it for collage and my classes are usually 3 hours a day. I am unfamiliar with the mac operating system which is why I am leaning towards the razer but I'm still undecided. Please don't suggest any laptop besides these 3 and money is not an issue
