I have been debating between getting a pro 13 or an Alienware i fly a lot and want something portable with a good screen been leaning towards the apple because i have a massive Itunes library with a lot of movies and wouldn't mind being able to watch those in flight. This would just be my first apple computer and would be new to the Apple OS. So for portability how portable and durable is a pro 13? And is the screen have a lot of glare?
