Reasons for Apple's success:

“Apple is constantly evolving,” - none of that going on here. A17 anyone?
"His first order of business: to drop costly projects and streamline the company’s focus."
What has Madmole said on more than one occasion?
"Apple came up with new ways to bring in revenue by getting people to consume microcontent,”
"Jobs saw an opportunity to target music fans who wanted affordable music but didn’t want to drive to a store"
That's not to say UI didn't have a role:
"Apple took a different approach to its first iPhone in 2007 by adding a multi-touch screen. The simple, yet innovative design revamped the style of smartphones and propelled Apple as a leader in mobile technology."
I rarely state my opinion, but while it would be nice to have a nicer UI with elements that can be resized and moved to various places on the screen - it hasn't curbed my 4600+ hours of enjoying the game for everything else it does so well. (And, I'm currently playing around with modding the UI! Watch out Stedman! That's a thank you btw...)
AND - - Android has been 'stomping' iOS:

It seems like 7D2D might be able to be compared to Android - because of modability.
(Does that make Rust more like Apple?)
