Col1: The RiscPC isn't manufactured any more. The A7000+ may still be manufactured, but it's hardly likely to be sold in any quantity. Likewise the RiscStation. Omega sales have been, shall we say, fairly limited.
I assume blahsnr is talking about future development and sales of new machines, perhaps to new users, not small numbers of sales for obsolete machines like the RiscPC.
This also leads us back to the question of why people who have bought new machines should continue funding RISC OS 4.xx developments that will be of no benefit to them.
