I used and developed software for RISC OS for many years and it was there I cut my teeth as an open source developer.
I wrote the very popular !Director application which let you customize your Desktop and add lots of nifty shortcuts. It could be expanded with BASIC plugins to do just about anything! It was distributed by the Arcade BBS to start with then Acorn User magazine put it on the floppy disk that came with the magazine.
Amazingly Director was written entirely in ARM assembler (with the help of lots of macros). I used to really enjoy writing ARM assembler and used to grit my teeth whenever I had to read the assembly output of the C compiler! I remember writing quicksort in ARM assembler as part of this (to sort menu entries) which was a lot of fun.
I still have a RiscPC under my desk, but I don't think I've turned it on for nearly 15 years :-(
As someone that grew up using Acorn Archimedes it's hard to express to those that were never involved just how difficult what has been going on here is or how surprising it is they have stuck at it. The overwhelming majority of us had left long before 2000 (even before 1995 really), and it's not as if there were ever that many compared to the Amiga or ST universes.
There was at least one program for the Acorn which is unique --- Cerilica's Truism --- it was a DTP application which actually simulated mixing inks and what inks would look like on various paper substrates (no need for the "C" variants of PANTONE spot colours).
I've always been curious whether choices in Mac OS X might have been (unintentionally) influenced by RISC OS. I believe there were a disproportionate number of Brits on the HI team at Apple.
The stand-outs to me are the use of blue folder icons and the Dock.
There was persistent noise even back in the 90s that the icon bar was inspiration for the Windows task bar in Win95. Quite the basis for it, or if it was nonsense, no idea. (HN has previously surfaced some serious Acorn related historical surprises, so someone here may actually know).
What has been quite surprising over the years is how violently many people raised with Open/Save dialogs hate the Risc OS filer and approach to saving and loading files.

I think we're getting pretty close to the point where hardware manufacturers can find a niche use case for these OS's - I put ReactOS and Haiku in this set - and build custom hardware just for these OS's.
I mean, I'm pretty sure there is a market for OS's that have not, yet, been encumbered with AI/Ads/spyware/etc.
Twenty years, but apparently no screenshots. How can they be serious about making a graphical operating system with no screenshots anywhere on their web site?

It’s owned by Avid now but it started as the work of two brothers on an Acorn Archimedes under Risc OS.

Paul Fellows later went on to be the CTO of AlertMe, which became the basis of British Gas' Hive service, and then Lowes' Iris product line.
