I have 10+ ARM powered devices in my house, and I don't even try to buy them.
Two smartphones (not iPhone).
One GP2X (I used to develop for it).
One TomTom (defunct)
With the exception of the GP2X, these are hardly far from consumer items. I deployed 50 Intel Atoms a few years ago - they worked fine for office tasks, no problem at all. A lot of people who have Intel Atom don't even know they do.
P.S. Intel Atoms suck for low-power usage. I know of precisely one "RPi-competitor" board that they brought out to try to capture that bit of the market, and it's very unpopular. Even Mini/Nano-ITX with laptop chips did a better job 10 years ago.
Power = heat. Heat = cooling. Cooling = expensive. A rack full of ARM chips in the proper layout will reduce costs and, so long as it runs PHP and Wordpress, that's a vast, vast potential saving right that just for a bog-standard hosting provider. And, yes, you can get Intel Atom dedicated servers. Check out OVH/Kimsufi (same people, first/second-hand kit - it's second-hand because someone used them for years already).
Maybe not your use-case, but I'd happily pay for an ARM-powered PC with PCIe, SATA, etc. connectivity and Linux.
Not to mention things like Spectre and Meltdown. I think you miss that some of the most powerful chips that people use today are from ARM. Most people never max out their CPUs and when they do, Intel stuff just dials down to ridiculous speeds nowadays (Intel are still selling machines which are clocked at 1GHz as "4GHZ" machines... they can maintain 4GHz for only seconds under normal cooling arrangements). But their phones and other gadgets are doing tons in software and ramp up past those speeds just for playing with silly graphics filters.
While you were sleeping, ARM owns the mobile phone market, tablet market, is already inside the Chromebook / mini-book market, the games console market, has Microsoft making Windows for it, basically has the IoT market to itself, and is now edging into the server market quite happily.
