It's funny that you think Android users are broke-ass nobodies. That's some reality-distortion-field fanboi nonsense. And it's also hilarious that you think phone apps are useful software that costs lots of money.
Most people in tech with high-paying jobs that I know are using Android, because it's actually pretty awesome compared to the locked-down walled-garden that is Apple. More than half my friends use Android or Windows. They use Android because it isn't as locked-down as iPhone. They use Windows because it runs all the software they want it to run. We also really don't care about Apple's blue bubbles.
No, Apple users are not the only ones with jobs. Plenty of Android users have plenty of disposable income. It's a ridiculous argument to make that Apple users have more money to spend.
>Do you believe that the vastly larger installed base of Windows guarantees more money for everyone?
I don't have to believe it, the market believes it. People vote with their dollars, and they aren't voting for Apple all that often worldwide. Plenty of wealthy people use Android and Windows. I'd wager that most big companies are still run on Windows - and I know this experientially, from back in the day setting up computers for major corps, it was 85% Windows, 15% Apple. Always was, always will be.
