I got caught looking at them and expressly told I couldn't have them. Well that and no one answered my sizing question, what's up with that, eh?
Only if you use a protective sleeve or if it's surrounded by a whole bunch of papers and documents. The briefcase is rather deep so a laptop alone in there would not be particularly well secured.
I like Calabrese, but honestly, if you want to get something from NMWA that is better designed as a working briefcase, I would go with La Portegna: http://www.nomanwalksalone.com/index.php/accessories/bags/sol-brown-carter-leather-briefcase.html#aboutmaker
The Calabrese is nominally called a briefcase, but at nearly 5" deep and without much internal structyre, it is, imo, really best used as an overnight or carryon bag.
Spain has an incredible history of leatherworking. The only reason that Italy has such a great reputation is the remarkably successful "Made In Italy" campaign. Spain, at that same period, had Franco, which was not as great for PR.
