I had to put in my two cents here. Due to a recent foot surgery and lovely "boot" I have to wear, my doctor recommended I temporarily use a rolling briefcase. I had one I had just been using for storage. I really liked my "samsonite" carry one. So, a few jobs later and I'm really liking this rolling bag (protege). Surprisingly, even with the wheels it's lighter than my old bag. This matters when your tendinitis shoulder is acting up! Maybe NNA has them too, I don't know.
