Summary: I like this bag a lot. I have been using it for a couple of weeks now and I have traveled with it during that time so I think I have figured out the pros and cons with it. I like the laptop compartment, it is well protected and fits my 15" MBP perfectly. The compartment is easily accessible. The main compartment fits a lot of gear/accessories. I had a couple of small HD's there along with cables. It does not have a configurable compartment, but you can fit a lot in it.
