TonyStill: Presumably their front cover is aiming at consistency with other Welcome Guides. Since the Iyonix Welcome Guide is in colour, though, perhaps they could include Chris' variant on the inside front page?
I would imagine that much of the existing RISC OS 3 User Guide would still be relevant for RISC OS 5. Scary thought! Maybe Castle should buy CJE's immense stock, and offer it as an option with the Iyonix.
AMS: Some people seem to see Castle advancing the platform (real ARM hardware, documentation, and all the rest of it) as a threat, rather than a positive development. Sad, really.
