Actually I didn't know of this before:

Yeah we were using ARM desktops back in primary school with Risc OS. Its quite fascinating that they are coming back.

Exactly, my family’s first PC was an ARM based Acorn Archimedes - https://en.m.wikipedia.org/wiki/Acorn_Archimedes

Our school computer labs had BBC Micros, the predecessor to the Acorn Archimedes and all ARM processors.

It’s funny to think back at how quickly that computer was out of date, we only had it a year or so before getting a Windows 95 PC. At about the same time we came back from a school break and all the BBCs were gone, Windows PCs in their place. Now we are all carrying around an ARM in our pockets.

Being from the Cambridge UK area it’s amazing the heritage Acorn produced. About 10 years ago I worked on a project that was being run by the original lead developer of RISC OS. The connections are everywhere.

And, according to a BYTE article from around the time of the launch, it could do FP math faster than a 386 with a 387 coprocessor.
