Android: Because I like freedom and efficiency over aesthetics. Besides, I don't have to redownload music just to run it on my HTC one. I also don't have to buy an extension just to use a microusb charger. It also isn't IOS, so that's a huge plus.
Iphone users are so desperate, that they fabricate pseudoscientific studies in order to show "proof" that iphone users are smarter. It's laughably pathetic.
