Having not seen very many reviews of this bag online I thought I would post one since I would've really liked to have read a few before I bought it. To start of with, the Nerve L is not a small bag. I mean it should be pretty obvious since this bag is made to fit a 17'' MBP that it isn't going to be tiny. The first picture shows the Nerve L(left), the Fossil Blaze Messenger (what I used to carry my old 15'' around in, its a prety snug fit for a 15'' in a sleeve, middle), and the Timbuk2 canvas messenger (right). The canvas bag has an almost obscene amount of volume since it is not partitioned in any way. The booq is much more structured. With the Booq nerve L I can fit the laptop (in sleeve), a Medium intuos4 tablet (in waterfield sleeve), a 1.25'' thick accordion file, and a tablet and still have a little wiggle room. This is with some small items in the interior pockets as well. I was actually surprised at the volume of the Booq since its depth is much less than the Timbuk2 The second pic shows the sleeve relative to the size of the bag. That being said the bag is not specifically/only designed for the 17MBP. The laptop sleeve is a good fit for the 17'', but it has just a little bit of wiggle room. If I move the laptop to one side there is enough room to stick my thumb in next to the MBP. However the combo of the size and the soft lining makes it a cinch to get the laptop out of the sleeve while leaving the sleeve in the bag. The third pic shows the mid-'09 17'' MBP in the sleeve. The fourth shot shows the interior of the bag with the laptop sleeve removed. There are 3 velcro-closure pockets on the interior of the front wall, in addition to a wide zippered pocket. The zipper pocket can easily accommodate 2 CD jewel cases side by side, I have the black recovery disks and manuals in their holder than came with my MBP in there right now. In the shot you can also see on the interior of the rear wall, the sleeve holder pocket/holster. The laptop sleeve slides into this and also holds it about 1'' from the bottom of the bag, suspended if you will. The pocket goes about half way up the sleeve and is decently secure at holding it. Secure enough that it never moves when I try to pull my laptop out of it. fifth picture show the interior pockets open.
