bluenose: You speak as if something tangible past an idea for the Iyonix 2 exists. I seen no evidence what-so-ever for such an assumption, especially given they appear to have been asking for UKP100,000 to "finish" it - that's pretty much the amount you'd need to design and complete it in the first place.
Your Linux idea is nice. How does it differ from the VRPC or RPCemu solutions, both of which essentially provide HALs bridging RISC OS's understanding of hardware to that of a host OS?
It's important to not forget that there are people still selling native RISC OS hardware, and they've made no announcement of stopping.
