Apple customers want whatever Apple execs tell them to want.
That might be true of some Apple customers, but I can tell you that I'm an Apple customer, and I assure you that I chose iPhone over Android because, based on my research, I think iPhone has a better security, reliability, and longevity story. When I'm ready to upgrade, I'll reevaluate the smartphone landscape again.
Apple tells them "thin is in!" and Apple customers believe that thinness is the most important thing ever.
Actually, one of the reasons I bought an OtterBox for my iPhone was to fatten it up and make it easier to hold. The other reason being, of course, protection, since the phone was pretty expensive.
You seem kind of unthinking and religious in your hatred of people who choose to buy and use Apple products.
