Update on December 2, 2011 - The seller, Wayfair were very nice and prompt in accepting my request for return. Only reason to return is the fact that, with my disability of not being able to use one hand, I found it extremely hard to use the laptop sleeve, which is located in the back of the main compartment, whereas the zipper for this compartment is in the front.

I bought this backpack to help me lug my laptop (12" HP Elite-book) on my trips. I cannot use my left hand. With only one working hand, I found it very hard to get my small, light weight laptop in and out of this bag. The laptop sleeve is way in the back and you need to move any thing in the front out of the way and hold it down before pulling the laptop out of its padded sleeve. Very hard for me. Also, there is really only one large compartment - the one where you would keep your laptop and folders etc. No place to toss general stuff in it if it is not small. I have an older Samsonite backpack I bought in 2004 that has two large pockets with a padded separator between them. The laptop sleeve is attached to this separator. I can pull my laptop out easily with one hand after opening the zipper. No need to reach deep inside to get to the laptop. I wish, it had wheels.
