It's because Android devices are marketed for nerds, by nerds.
The entire marketing department of a dozen different phone manufacturers is supposed to be nerds? It is nerds that are supposed to be responsible for putting out the vapid, shallow Motorola commercials? However, the source of this "it is nerds" refrain is quite clear: it's Apple's marketing department. They are trying to portray Apple as the "easy-to-use solution for the rest of us" while painting everybody else as being run by nerds for nerds. Really, man, stop being such a stupid Apple tool and stop doing their marketing for them.
The iPhone ad shown in the article is actually perfect. It answers why, it shows what you can do and it doesn't go on and on about things users don't directly care about, like processor speed.
And that's why Apple keeps touting their specs on the rare occasion where they are actually ahead? Retina display?
And the "answers" Apple gives are largely lies: lies about capabilities that their products are supposed to have and others don't, lies about who invented those capabilities, and lies about freedoms and future developments.
