The speed limit analogy I can sort of see if I squint and I think highlights the reason people buy Apple: they want simplicity in their life. They don't want to monitor the speed limit for every road they drive down, they just want to know that if they're driving they're doing so at the recommended speed and won't end up getting a ticket (or crash!) because of an unnecessary choice (speeding).

Of course if we extend the analogy further: if it's a car then the automobile industry is dominated by just two car manufacturers and they both exercise a level of control over what you can and cannot do with the car. And people need cars, so they make a choice between two unoptimal choices.

I was an Android enthusiast, bought a Nexus One the day it came out. Then a Nexus 4, then a 5. Did custom ROMs, the lot. Ended up switching to Apple for simplicity around messaging and FaceTime with family/friends. I haven't ever looked back, I can't say there's anything I miss. Except the notification system maybe.
