Need help choosing a backpack

I all ready have the lowepro vertex 200 which is great to take all my gear witih me.

I'm a student and I want to take my camera with me (not all my gear, only 40D 24-105 and 70-200 2.8).
I also have to take my laptop macbookpro 17" and a map like this: http://www.offeq.be/vo​orbeeld/35.0355.jpg with me.

I all ready saw a bag with the lower compartiment for a camera and the above part for some random stuff.
And can it be a good looking bag?

Does someone has a idea which bag could fit my needs?

Thanks!

Have you checked out the Tamrac Aero Speed 85? I purchased one of those and love it so far. Holds a 17" laptop, plus photo gear easily.

Thank you for the reactions.
I ordered a dakine mission photo woodland. I hope it will be fine for my needs
