Both these guys saying stupid and crbbing about battery life must be 40 plus?
Your point is? As a 49 year old I love my all singing all dancing Samsung Note, I like tablets (my family has 3), I like laptops (2). But because of the crappy battery life of all of them I keep a very basic mobile switched off close to hand just in case of an emergency. All of the rest aren't happy unless their charging port has a USB cable/ charger in its ass.
Why not use drones?
I would guess the size of the drugs packages they have in mind would dwarf the capacity of anything but a proper Predator drone to carry.
It is easier to write an incorrect program than understand a correct one.
