>>51027083The 'nurse' is much-maligned, but it's practical as fuck. I, too, keep my phone in my tablet bag. I have a removable battery in there, too, and it kicks the shit out of any replaceable battery. It can charge my iPhone EIGHT TIMES, and it can also charge just about anything else, as long as I also carry USB and Lightning cables, which is easy enough when you have a tablet bag.
Beyond that, the bag enables me to carry a multitool, medicine for headaches and allergies, a mechanical pencil, stuff that you'd just be dumb to not carry.
