So I just bought a case to carry my macbook/textbooks in today. And i was just wondering. The macbook casing isn't exactly the toughest stuff in the world, and when i put a few of my text books and binders in the bag along with my macbook I just sorta get the feeling like I'm gonna crack my screen because there's too much pressure. I look at my macbook and it's fine every time i pull it back out, but i just sorta have that "new buyers feeling" where i want to make sure NOTHING bad happens to it. So what do you guys think? I mean it's not crammed up to the point where i can't close the zipper, but i just get that feeling like somethings gonna happen, but am i just being a bit too worrisome? any advice will be much appreciated. Thanks.
