Freshmen!
Oh okay. Welcome to college!!! By the way, just so you know college students don't really bring their textbooks with them because it's not really needed in class (unless specified by the teacher). Most students only bring their pens and notebooks with them in class plus some personal materials like phone and wallet. If you are taking notes with your macbook instead of using pen and paper you might not even need paper notebooks like other students. So, on a regular day in school you might only need to bring your laptop, pens and other personal materials with you. Honestly it not that much and you might find yourself not needing a backpack with lots of compartments.
I have an LL Bean book pack, with an Incase sleeve that slips right in one of the sections and protects my Macbook from being crushed by my 10-lb. Calculus book. I ride my bicycle to school, and trust my sleeve and backpack completely.
Former college student, but I still carry around a Targus laptop backpack-- there's a built-in sleeve for a laptop. It is not, however, particularly waterproof, so I have an 'anti-environment bag' constructed from two ziplock bags and duct tape that I used with my old Sony Vaio (and which conveniently is also the right size for the Macbook I carry now).
The only trouble with it, I found, was that there were a lot of other people with the same backpack, which could mean two things:
* Confusion between your bag and someone else's.
* Everyone knows you have a laptop backpack... which might contain a laptop.
Neither became a problem for me.
By the way, just so you know college students don't really bring their textbooks with them because it's not really needed in class (unless specified by the teacher).
I <3 L.L. Bean, being from Maine and all
I use a Belkin Sling Bag like this one here:

The sling design distributes weight really well, and the laptop pouch inside also has this 1/2" thick or so plush cushion that can be removed, or left in to protect your laptop from any other stuff you have in there. My 14" Acer notebook sits snugly in it, and feels very safe and secure.
It has lots of little pockets on the inside for misc. assorted stuff, a couple of pen holders, a special pocket for your ipod with an outlet for your headphones, etc. On the very padded strap on the front, it has a good quick-release connector, and a little zippered pouch for your cellphone. I got it for $39 at Wal Mart.
PLEASE do not put your macbook in a laptop backpack.
The pressure affects the screen, and the sensitive optical drive will caput.
trust me, this happened to my poor Olga [my white macbook- my baby]
use another shoulder-strap bag, like this one
