I have the old white mac book, and it works perfectly. But, this year I am at law school and will be doing research and taking classes, and I cant take the exams with this macbook because the system requirements doesnt match the req for the examsoft, also it is quite frustrating to carry the macbook all day long... I was planning to buy the 11 inch Macbook Air, but now I am worried that it might be hard to read during exams and more importantly in the bar exam. Any suggestions? I am planning to either buy a 11 inch or 13 inch.
