Acorn had a tendency to be ahead of its time. Our first home computer, the Acorn Electron, could be expanded with a 3.5" floppy drive. Later, when we got a PC, we moved from 3.5" to 5.25" floppies. That was my first disappointment in having to make a step backwards in tech.
The Archimes' successor, the RISC PC, could even have an Intel processor as co-processor. Or, instead, a card with 4 or 5 more ARM processors. At the time is was probably the cheapest way for a consumer to get a multi-processor machine.
I bought a fully stacked A440 when they were released, many thanks to the kindness of a deceased relative and much to the dismay of it mother who said I should have bought history books and art materials instead.
Really if they had something RISC OS 2 quality on day one, which would have been a monumental feat like the hardware was they’d have done better. I enjoyed every moment of using the machine after RISC OS 2 came out. Before that I was slightly scared I’d burned a monumental amount of money.
That would be 22 bit, which seems quite unlikely. Perhaps you're thinking of 4096 (= 2^12 = (16)^3)? It seems only 256 of them could be shown at once and only 240 could be modified [1][2][3]? If those are correct then it is more limited than VGA, which could show 256 colours chosen from 262144 (= 2^18 = (64)^3). Some Archimedes resolutions were more like low-end SVGA though [1].

4096 colours. :-)
Otherwise, yes, pretty much. I bought a 2nd hand A310 in 1989 and it easily outperformed the fastest machines my employer sold (e.g. the IBM PS/2 Model 70-A21, a blazing 25MHz 80386DX with 64 KB of secondary cache) by a factor of about 8×.
Given that the state of the PC OS art at that time was MS-DOS 3.3, which very few people bothered to put Windows 2 on top of, Acorn's RISC OS 2 was astonishingly advanced, too.
Anyway much of the commercial success of ARM must be down to Robin Saxby who was ARM's first CEO. His interview with Charbax is fascinating [1]. He inherited a company with two customers, one of whom was failing, some interesting IP but not much else. He seems to have had a relentless focus on providing customers with what they needed - for example providing the Thumb 16 bit instruction set to reduce code size when potential customers such as Nokia were reluctant to move to 32 bit designs.
It's also the first true ARM/RiscOS laptop that has been made since the original Acorn A4. That machine was the first portable ARM device ever made.
Operating systems have been born and died between the arrival of these 2 machines.
It has clear advantages for video editing, especially on export given the arm chips often just spend time decoding video and encoding is quick cheap and streamlined.
can't speak for other industries, but as a dev most stuff in apt is arm64 compatible and therefore runs fine inside of a container on android (this was disabled with android 10 unfortunately)
In fact, the ARM was designed for the Acorn Archimedes, and that’s why no desktop, or server, or anything, used it before the Archimedes - ARM stands for “Acorn RISC Machine”.

While the chips were indeed created specifically for the Archimedes, it would have been possible for some other company to have made a machine with them before Acorn.
I understand power usage is a big concern these days, but I can't help but feel this aspect of arm is greatly overlooked and that the push towards arm devices is also partially inspired by the ability to lock down chip designs to a greater capacity than x86_64 chips.
Just look at the existing fragmentation among arm powered devices as is. I don't really like the thought of what an arm powered future could look like.
I really wish I could remember what video it was, but I remember years ago watching the ceo of arm present a new chip with built in emulation technology, that theoretically, would have allowed multiple operating systems to run at once or something. I remember the person talking to him asked if he forsaw this as the future, and he just laughed and said oh no, no manufacturers would never dream of allowing this and furthermore they'll likely use this technology to further specialize and lockdown their chips.
It may be personal bias, but since then and other things i've learned about arm, I've just had this lingering unease as to what them gaining dominance would mean to general computing.
Apple has shown pretty clearly they see themselves as a consumer electronics and services company above all. If all the "professional" users who rely on Logic or FC or Apple in general jumped ship, Apple wouldn't likely notice it in their bottom line (loss of mindshare not withstanding). They have no vested interest in catering to these users and have produced hardware intended for them as an afterthought. The high cost of hardware and absence of middle tier products that make sense for these users is just icing on the cake.
"Professional" users of Logic or FC have little leverage to affect the course of Apple one way or another (unlike a more focused company whose business model is catering to these groups).
On the other hand Apple pro users do have a long history of being abused by the company so they might be alright with it in the end.
Anyway, I'd be looking for an out if I were them.
Mac software will continue to rely on proprietary APIs. Software that didn't is most likely already ported.
There have been multiple attempts to build an x86-based VST host, over and over.
It will be about 1000x easier to do, if everyone builds for ARM.
However! ARM DSP/synthesis is fraught with minefields. One mans ARM is not a SHARC, etc.
It should be noted that there are already mainstream synth manufacturers shipping ARM platforms .. and there is no virulent unruly lunatic fringe like the synth lunatic fringe, btw.

That reminds me I want to try the Manjaro build out. I've heard good things. I actually really liked the ChromiumOS build but it did take some getting used to (I'm a ChromeOS n00b)
It was a ‘compatibility calculator’ where you put in the names of two classmates and it gives them a percentage of love between them. We used to do it on paper, taking all the instances of l,o,v,e in each name then adding them to the number adjacent until you just have one number.
It went pretty viral within our class of 20.
My favourite app was called Euclid, which was a 3D app like Blender. I built cities, an American semi truck and all manner of stuff. My love of gaming and 3D continues today.
Back to the article: what author kind of missed is that ARM was Acorns spinoff of the CPU business since their computer flopped.
As an owner of one, I found it interesting but the OS was really odd (for example . was the folder sepeator which caused "interesting" problems for C compilers). They also promised high performance x86 emulation using their RISC magic but failed to deliver.
Transmeta was eventually able to deliver what Acorn promised, but that came 5-10 years later.
Anyway, what finally saved Acorn was Nokia and Ericsson picking ARM up for phones due to low power usage.
And I'll be able to run BBC BASIC natively on a Mac.
One thing the author seems to have missed is that what sets Apple apart from most ARM based SoC developers is that Apple has an archicture license. They don't use the cores provided by ARM. They implement the ISA by themselves. And they are really good at it. Look at the A12 chips for example.
The ARM A-7x cores are quite powerful. But we can be sure Apple will take full advantage of the higher TDP and incease performance in the cores beyond what ARM provides in their cores.
Also, expect more CPU cores/device than what Intel provides.
The thing about the cores is alo true. Tighter integration with coprocessors for AI/ML, Crypto (and improved ability to shut the down, increase/decrease clock speed etc) will also be a boost compared to x86, where it is either done in SW of using an internal or external GPU.
But to answer the question from the title: Since people wonder about the MacOS experience on ARM. As the article rightfully says phones (thus the probably most used end-user computers) are on ARM as well and are being used for many things desktops were used before ... :)
Another curio, for a while Intel made the fastest ARM processors, after they bought StrongARM from DEC...
These ARM servers however.... (32-core and 48-core ARM processors)
Seeing the Archimedes screenshot with “Apps” in the taskbar made me realize I was sorely wrong. Does anyone have any interesting history on who was first to start using “Apps”?
Fond memories of the platform. Lander is still hard as fuck to this day...
The Archimedes was the first ARM desktop computer.
An important distinction I feel.
Ugh. These kind of articles annoy me.
Also I think I’m waiting for apple to put a freaking touch screen and keyboard on the same product. (Touch Bar does NOT count)
Then again, I’m an ARM desktop user already!
Why wait for Apple? idk, let’s wait and see.
