If Apple has to raise prices on their hardware to stay is business, that seems much fairer that using addicted mobile gamers to subsidize hardware for everyone else.
Also, my experience aligns with this too. I dont game on my phone and basically use default apps. I use the United app to book flights but could easily use the mobile website. Same with Twitter
Your purchasing habits are not indicative of the mainstream; further, the iPhone isn't priced based on cost to the cost to design or manufacture.
This is also entirely hypothetical because Apple has really good margins on their phone sales.
