Appreciate you love RISCOS but I have to look at what I'm asking the computer to do. It's a tool afterall. I started life in RISCOS and then in parallel used PCs. In 1998, I switched over to PC exclusively. In 2002, I switched from PC to MAC because of OSX and it's Unix heritage; so I am not biased towards any platform.
Back to my point, the computer (and the OS) is just the tool. What matters to me are the applications and how both the hardware/OS and apps work together.
I have been watching the RISCOS platform for some years on the bench and even with the latest high speed models and great improvements, don't intend to switch mainly because the MAC does what I want it to do in the most producive way possible. Windows XP has moved on too but is still pants when compared to OSX and indeed BEos and RISCOS.
Why is it the little guys with the great products never win - Apple included (it's tiny compared to WinTel).
The ONE thing Apple have that Acorn didn't, is presence in the face of the mighty WinTel monopoly. Acorn never had a constant stream of revenue coming in that was stable.
Having said all that, I'm glad a small but dedicated community of enthusiats exist and it really shows that Acorn made the WRONG decision to give up. There is money to be made in the Acorn market.
Here's a thought, why not use a UNIX core and write all the necessary RISCOS layers on top - just as Apple did. That's where your gonna get your killer-apps from. If you don't believe me, watch Linux space and see MS quake in their boots.
