Just intellectually curious -- why is that saddening? My thoughts are, people can do what they'd like with their money.
I mean, okay, maybe farting was funny when I was five. But if you're old enough to own an iPhone, you should be old enough to have a slightly more refined sense of humor.
Granted, "refined" is extremely subjective and arbitrary, but you asked so there you go ;)
Outside of your self-righteous indignation, of course.
