On my phone, I have a faceid requirement on basically any app, so getting it ripped off my hands would be just a minor inconvenience.

Laptop on the other hand... Many times working on the train i've been thinking about some accelerometer based emergency lockdown. Can't be that hard to do.

There is software to shutdown/lock based on removal of a usb device that you have looped onto your wrist.
