Any reason is a good reason...
I just spent a month in Europe with the FJN, and found some surprising uses for it. I loved it!
it is good for a lot of things, but I found that I also used it as a kind of small carry bag.
You can put a paperback in it along with the notebook, and the outside zippered picket can hold a PDA (iPod Touch, in my case) or even a small point and shoot camera (not too big, or the fit is tight).
i also found it made a great "in-plane work kit"--I kept it in one of the end pockets of my Aeronaut, and then took it out in the plane to hold my reading and notes. It can hang from the strap from the seat in front, as well.
So in brief, this might just be a very good gift for a professional traveler.
