Show him everything your phone can do without having the need to root... (BTW, You DO NOT need administrator rights on your Windows PC to have it do just about everything it does, same applies on android phones)
"Lock down" on an Android phone is like being put in Australia (penal colony) compared to an iPhone in an altoids box, in the trunk of a car, in an underground garage, in an unknown building somewhere in Bangladesh..
Besides, you have a kickstand... ok ok so he can lean the iPhone up against his AT&T bills to get the same result..
