Thanks John for that generous offer it is much appreciated. Rather than put you to any trouble I might be able to "purloin" a copy from my friend for a longer "test drive" as it were. A surface skim showed it to look well produced - a more detailed review might show if the content is up to the same high standard.
I wouldn't call the availability of USB 2 support, or the charge for the upgrade to 5.12 as being unnewsworthy though. It's also the not inconsiderable matter of perception. Drip-drips of upgrades reported give the impression that something is being done - if nothing is reported then potential buyers of Iyonix may believe nothing is happening and that it is somehow less supported than other RISC OS platforms and that would IMHO be unfair.
