Hello guys, I am going to buy my first MacBook Pro ever this week. I can't really decide if I should go with the old MBP or the new one with retina display. The reason why I can't decide is because 1. The Retina version only has 128gb ssd while the old one has 500gb HDD. 2. The retina version comes without CD/DVD drive. So please help me out on this one, which one would be the best for me, as it is my first MacBook and I just need it for school and when I'm going to a friend's house etc.
