I can't speak to NYC but in SF you absolutely will lose your shit. I have had coworkers get their cars broken into midday after leaving their backpack unattended for an hour or so. Friends have had their backpacks yanked from between their legs on Bart as it entered a station. These are not situations where these items are just laying around, and they were still taken. Coworkers have lost their laptops at bars or coffee shops because they got up for a few minutes. It could be that the value is so well established in this area; if you steal a backpack you are almost guaranteed to get a Macbook. IDK if that is similar in NY.
