After a few weeks in use I can now draw an initial conclusion:
+) Lots of room! It fits all of the above described pure, there is even room for other things.
+) The front compartment is clearly designed and the few small compartments completely satisfy me.
-) The zipper from the front compartment has initially somewhat pinched and I really had to "practice" until I figured out had the knack. Meanwhile, there are no more problems.
+/-) The sheer size of the backpack has initially a bit overwhelmed me. One thinks first, you walk with a ton on the back of the area. But it can get used to after a few days.
Overall I am very satisfied with the backpack! A lot of storage space, price / performance is super and if one is aware that one has "more" on the back and one that does not bother, this backpack is right.
