One of the key differences between Apple and Android - for me - is that people who buy Apple generally buy into the hype created around Apple. And the reverse - people who buy Android don't buy into the hype. I can't say I have seen a single Android advertisement like I have seen iPod/iPhone/iPad ones. So there is no need for an Android John Gruber; all of the hype of "The Smartphone" has already been done. People know what's on offer, and base their decisions now on utility and price.
