1. What is the maximum size and speed of hard drive that can be fitted internally into the latest MacBook Pro? 2. I was in John Lewis today in Nottingham and was looking at the 15" and 17" MacBook Pros. I was looking in carefully at the screen brightness and quality and it became apparently clear that the 15" has a much brighter and sharper display and looks even across the entire display where as the 17" looks faded and not very sharp. Am I correcting in seeing this as the case? Would it be better to get the 15"?
