Excellent bag, but ... BUT!

I was looking for a bag for transporting and my classes and my laptop with me my faithful cooling rack 19 ".
And all returned! Support stuck a bit because of the rubber, but otherwise it's nickel.
The bag exudes quality, "workstation" is good but not great (there could be more pocket just like a key ring).
At the padding for the back, it looks to be the quality but I did not done a precise opinion. I would return in a week or two to give a final opinion.

Black spot which would withdraw its 5th star: pimp his pocket. I would have appreciated a secret pocket in the back padding to how Case Logic: /

EDIT:
That is now a good time I use this bag, and I must say it's solid. 12kg on your shoulders and I feel nothing. I feel like carrying heavy bags, no more. The padding is really nickel (even without this pocket ...) I have worn for nearly 3 hours in a row this bag without having back pain (first for a bag with such a weight on a back as damaged as mine )
He resumed his 5th star, just for comfort !!

EDIT 2: It will eventually lose two stars after almost a year and a half of operation, the impermeable layer on the underside of the top of the bag in hand peanuts! There are only the canvas there, protecting only too little laptop just above :(
