It doesn't work that way. If you have time to think about throwing your tablet, then you have time to think about running. Please trust me, it's too sudden for that.

Unless... maybe if you're travelling in a group then one person could hold onto the tablets of everyone each day, only giving them back if they're needed? That way they won't be on most of the people for most of the daylight hours.
