In reply to mrchocky:
My well-intentioned attempt to lighten the mood seemed to fall flat. However, I didn't think that the idea of RO5 on a Palm was as silly as you seemed to.
"and a suitable video system":
I agree that one would need access to the Palm specs (which might be a cost issue) but it's likely to be much simpler than the Iyonix nVidia, hence a simpler job to produce the HAL. After all, the "bulk of the device driver implementation remains in the RISC OS modules" (forgive me quoting at you). So a simple underlying video system is likely to be easier to map onto. Remember that John told us that much of the Iyonix work was concerned with getting the nvidia card to intialise.
"proof of a market...to make it worthwhile":
You are, of course, entirely right about this. It's a risk, made worse by the provision of hardware easily priced-up in PC World. Would the RO aficionados pay a very visible premium of (guess) UKP120? I'm pleased it wouldn't be my money being gambled on that.
Finally, at the risk of being accused of saying 'Ya boo', I was pleased and amused to see PDAs mentioned in the RO5 modernisation story. Mine was intended as a humorous aside but, remember, 2 years ago few would have believed that CTL could produce the whole RO dream: 32-bit OS, HAL, XScale, USB, PCI, modern graphics *and* a video driver. I don't think I'm damaging the market with this little dream.
