In the main dwelling:
some documents, 1 notepad, pass without problem using the place left by the PC is thin.
In the pocket outer bellows:
The small charger, cable, keys, etc .. writing materials find their place too. A little mouse would by against difficulty being accommodated except removing something else (the pocket opposite must be empty).
The pockets are a little too tight in this compartment to thick things, or to get his hand and go catch that is at the bottom. Except for the mesh pocket where you can put things like thick charger, mouse etc.
Note also that the size of the bag is suitable for a 15 "6 last generation but no more. So I had to set the scratch separator as the safety belt ... what is ultimately useful to retain the PC because the strap is too biased.
The device protection bag is a good level (rather rigid and thick - although there has better).
2 pads on the bottom would have been useful to reduce dirt and any moisture.
But this is not too annoying anyway because you can keep the shoulder bag with padded shoulder strap good.
