Too much bags! Help me out here plz

Hi there,
I purchased a Clevo M860tu recently and I need a backpack to fit it.
(Dimensions: 364(W) x 269.5(D) x 29~41(H)mm)
I would like to use the backpack for school so it needs to fit 2 binders or a binder and a book. If I go home I'd like to put my notebook in it + a binder or a book, and I don't want my notebook damaged from the binder or book I put it in.
Oh another thing... if I put a binder or book in the space that's originally intented for a notebook, will it damage the padding inside?
I usually don't care about style, only quality. But please don't suggest anything hideous, I do have to run around with it a lot (off course taste is a personal thing)

I looked at that huge thread with manufacturers but it's just too much :s
I live in Belgium so if anything ships here and fits my requirements, let me know

Thanks!

 

My Targus Voyager serves me well. However, I find that it fits my laptop+1 binder + 1 thick textbook and only 2 thin textbooks which then leaves me with little room left to place a lunch or something of the sort.
I also purchased the Hey's 17" ePac Roller. And honestly, I think that it's an excellent alternative. Sturdy materials, well padded, and most importantly, you're not putting any weight whatsoever on your back. I can easily fit in my notebook + 2 binders + 3 thick textbooks. Two fairly spacious pockets are still available (laptop compartment, textbook compartment, and two spacious pockets, and then 2 fairly useful side pockets) and even more at the side! Pulling on it is quite easy, I can use two fingers to pull it and not really have any stress whatsoever.




The laptop goes in a compartment at the side.
