Sounds like you're missing his point entirely. He's not even remotely saying that knowing the processor is important. He's saying the kinds of people who do more research when buying a device (people who know what processor is inside is one way of qualifying that) are less likely to be confused about something utterly basic like knowing the difference between an iPhone 4 and a phone with 4G.
People who realize a basic truth, knowing the details helps you make better choices and achieve better results, are going to have the curious mind and appreciation for facts and information to know that "phone version 4" and "a phone with 4G service" aren't the same thing.
Now I don't necessarily agree with him saying that Android users are smarter than iPhone users, but there are huge chunks of people who buy the Apple product only because it's more expensive and because they're hungry to be recognized as owning the "cool" or "luxury" brand. Me, I don't give a shit what other people think about my phone. I had an iPhone 3G for a while, now use a Galaxy S, but will probably get an iPhone 5 simply because Android is too glitchy and buggy and immature of a platform to run like it should. It's too busy stumbling over itself to work properly.
