This doesn't matter. Just because they earn more revenue, it doesn't make their products any more appealing from user's perspective. When you are selling the most expensive devices on the market that cost significantly less to make than competing devices, and figure out how to sell lots of them (which they did) it's bound to happen.
Do you know that in China, to make a phone sell it has to either have a gold color option, and Android phones NEED to have 8 CPU cores? Qualcomm changed their whole roadmap and design for their custom core (instead of 2-4 wide, awesome cores they will use 4-8 of average efficiency) just because of the growing Chinese market and.. Mediatek being considered superior there because they had a 8-core (although super shitty) CPU there first.
This doesn't make such phones any better, but people are buying them almost exclusively. God knows why, but they do, and the world wonders why so many gold-colored phones are appearing everywhere, even though it doesn't seem like anyone would like to get caught using one from our perspectives. So the fact that something sells well to some people doesn't always make it an awesome choice either.
In my opinion, each to their own. I have an Ipad Air and while I like the hardware, I consider it the functionally challenged/retarded tablet for youtube videos and web browsing when it seems more cozy than reaching for the PC. I can't count on it to get shit done, or be convenient for general tasks that I use my computer for. While Android phones are just phones and not as convenient, I can get shit done there when needed and have peace of mind.
With Ipad, I once took it to a business trip instead of a laptop. It was hell, spending half of the meeting paranoid, trying to download that power point presentation and make final corrections to an excel table. I downloaded a browser that allows to download files and it was super slow, when it finally worked, it crashed my Ipad, after restart MS Office didn't launch because of some common glitch I was googling there. I had to ask someone to download a file from that website, atach it to email and send to my private gmail, and then managed to download gdocs and open, although it made it look messy and wasnt a convenient process as well. And they're such basic things that on Android would be natural - just download, open and edit. If you wanna send something, you do it easily in so many ways.
I have all of my work files grouped in folders on my phone's SD card and I can easily access all the information there at any time, and they're shitloads of different file formats. On iOS, I couldn't even begin doing that.. because there is basically no way to store files. So to me, I still like using my Ipad these days, but grew to see it as a very primitive device if it comes to usability, but it's quick to use for basic entertainment and googling.
Since that story, however, I'm even more paranoid with iPads, and use them only when there's PC around. In reality, it's not leaving my house, and spends 99% of time on my sofa for when I wanna do super basic things like quickly check something on the interwebs. For me, it's not understandable why Apple chooses to cripple their OS as much and how they can get away with it. I consider myself a minimalist, I keep only what I need/want on my phone, so half the stock apps are gone and I have maybe 15 installed in total. I appreciate that Android allows me to customize, but I appreciate having the option to do things I might need to do, and wouldn't feel comfortable not having such option, especially knowing it means paying more. What seems logical would be if Apple were like "ok, we've got a product that won't do as much, and it's overly tied to our ecosystem, but because of that you get it for cheaper and it's nicely designed". However, it's the opposite with the price part. It's just not reasonable, logically. But I understand that Apple created their own reality around Iphones, that affects Iphone buyers, and people with very simple requirements can actually be happier using those products. I also recognize that I'm not one of them. since design wins are not worth the rest of the whole package.
At this point I really don't care about the Apple vs. the rest of the world thing since I owned a Macbook Air and still have Ipad Air, which are really greatly designed pieces of hardware (also tech design), but I don't consider Apple's software to be on par, or Iphone's hardware to be on par with what I can easily get elsewhere. That's why for me, the Iphone is like that golden Xiaomi, or 8-core CPU that doesn't do much work. Even though I can observe it selling and having its fans, it's just not something I would recommend to a friend - because people buying such devices have their minds simply set on it, and don't give it much thought, they just like the idea, and hey, I can't argue with that, it wouldn't make sense, I sometimes make some decisions just because I feel like it as well, even if someone tried to convince me logically not to, it wouldn't work and I'd be happy in my bubble. Some people just have the convenience of being able to stay in one, and they're happy there. It's all good unless they're trying to claim there's nothing outside of it though.
Just my story, after a long break.
