I thought Castle were trying to sell RISC OS/ARM designs to larger speciailist/mass-market customers? Has this strategy been revised to merely selling a few 'bespoke' Iyonixes to the RISC OS market?
Surely something designed primarily for Customer X's consumer widget could have the side effect of being a cut down Iyonix in disguise? If it had been a tad less limited, a Bush Internet box could have been a good A3010-level option for example. Acorn might even have brought a Stork portable to the RISC OS market if another deal had gone differently.
Imagine something limited to processor, graphics, USB, maybe firewire? That's all an iMac has, after all.
