Does "Intel Inside" sound familiar? That's because it worked amazingly well, and people chose Intel over AMD back in the day just because they "felt" better about it. Some even chose it because they didn't want to get AMD shamed ("Aw poor person; they could only a afford an AMD.").
Not saying Intel CPU lineup wasn't better than AMD's product, (especially at the height of the marketing program when laptops used to have "Intel Inside" stickers), but a lot of people didn't even bother comparing. They just chose Intel-based computers.
And that's the story of how so many people I know ended up buying a PC with a crappy Celeron* (I know, I know, the new ones are better).
Sure, CPUs are harder than iPods to market to consumers. Most haven't a clue what ARM Cortex-A7 is. But, that could be the issue. They need to step up their brand identity. They also should probably tell people that ARM doesn't actually make hardware for consumers. They just design the architecture and license that design to silicon manufactures.
Most people knew they were buying an Intel. Most people don't know they bought an ARM. They could do better.
*: I assume some bought them because the salesman at Best Buy said "dude, Intel's are what you want. AMDs are slow."
I'm not sure that type of marketing will happen again though. Since then, computers have gone further down the path of being an appliance. What's inside matters less than what it can do. If Apple releases a MacBook with 1-5 days of battery life, no one will care what's inside.
