Interestingly, the same phenomenon that makes people write those emails can make them "double down" on a tech choice. A friend defaults anti-Apple so refused to buy the "Jesus phone". After four Android phones, each less reliable than the last while his sister's still rocking an iPhone 3GS, he switched last week ... To Windows Phone 7. He just paid $500 for a phone that, 3 days later, was announced would not be upgradable to Windows Phone 8. All because he is determined that Apple users are smug fanboys.

(Personally, I think he should have gotten a Google Galaxy Nexus if he wanted his sister's mockery about constant obsolescence and non working hardware to stop.)
