I'm guessing there's a bit of source bias here. I'll buy that Windows won't be dominant in 10 years, but defaulting to Apple doesn't seem backed by the data presented.
Apple won't dominate the corporate space because then they would have to support the corporate space. They know if they do that their products will be common, and they couldn't charge the premium they do. Then the people that demand corporate support their Apple products wouldn't be rebels sticking it to The Man. Would doctors and C-Level wannabes really feel special if they didn't have to throw their weight around to get IT to accept Macs? If that common, dirty, IT troll just sauntered up from the basement with a fully supported Macbook Air ready to go, it would take all the "I feel SPECIAL" out of the experience. And that is what Mac users pay for.
I refused to buy Apple products for 15 years. Recently I grabbed a whole set of them and honestly, there's only one thing I can say. It just fucking works.
I've been using Linux/Windows for the better part of two decades and I'm just at a point where I don't care to tinker anymore unless I have to, I just wanna have stuff that works especially when it's related to work stuff. Apple stuff is just reliable in that sense, oh my Android phone decided to crash on itself? Yeah my iPhone has had 0 crashes all year I've owned it. My M2 Macbook Air has superior battery life and portability at a more reasonable price than pretty much any competitor on the market?
Yes certain Apple things are beyond stupid expensive, Hello Apple TV 4K 128gb being £180 on launch?
But when I want something to work and not have to think about it, the apple stuff fits that need.
I think both of these assumptions are wrong. I think most apple users are just people who aren't "computer people" and want an operating system that just works to do the things they want, and are ok with paying extra to not have to worry about drivers or linux/windows issues.
Of course there are apple fanboys, but I don't think they are the largest subset of users.
Not necessarily Apple being dominant, but the only thing that you need is a Web browser and no one will give a shit what you run that on, Windows, Mac, Linux, ChromeOS
