I have one on my bathroom mirror, one on my dead laptop and one on the window of my horse trailer. I don't put anything on my truck except my parking sticker for work and even then I balked at it until security threatened me with a tire boot unless I put it on the outside of the glass of my back window.
When I got my original iPad awhile back, I owned a Dell computer, so I put my Apple sticker on that laptop covering the Dell symbol. I even left it on there when I had to ship it back for service because the hard drive died. I'm sure the people at Dell really loved that!! hahahaha When it got shipped back to me there was a little scratch in the sticker....angry Dell employees...grrrrrr
Since getting my MacBook Pro my husbands hard drive in his Dell computer died, so now he has my Dell, which still has the trusty Apple logo covering the Dell.... So at quick glance you would almost think we own two Apple computers....hahahaha --->unless you look closely....see attached photo....
I felt the best place for them was in the box the iPhone came in...unused. Every iPhone i've ever sold still had the stickers in them, and i have an apple sticker on my car that was from one of the first iPods i ever bought, lol...still going strong so many years later!
