I think it's more a very lame flex. Macbooks were expensive and if you were walking around the office with a Macbook it was because you were important enough to convince management to buy you one instead of some crappy Dell. Eventually enough people get Macbooks that you need another way to stand out so you slap a bunch of cheap stickers all over it to show everyone, "See, you coddle your trophies. I beat mine up because it's just a tool and I don't care. I'm too busy gettin' it done!"
