> It's probably a lifestyle choice, but if I were to feel unsafe using a laptop in a space, I probably wouldn't be able to focus enough to work You may have misunderstood the premise. I don't want to live my day-to-day life with a laptop on me 24/7, but I can tolerate a pocketable computer. Regular life involves activities in places without lockers - like typing up a dissertation chapter on the train to a ball game, or parking on streets that have occasional car break-ins, to have dinner with friends. The idea is to make spontaneous computing on the go possible; so the device pretty much has to be on you all the time and everywhere, and I don't think a 13" laptop is a reasonable choice for that.
