It may be worth pointing out that the Edit problems described in RO 5.05 were only temporary. They were not present in versions of RISC OS up to and including 5.03 (I don't know about 5.04, but probably not there either). I upgraded my own machine straight from 5.03 to 5.06 and never saw any of these Edit problems. The point is that Iyonix users didn't have to put up with these bugs for over a year; they were short-lived and the result of a short-lived problem that was corrected quite swiftly. It's a pity that users such as Martin, who bought a machine while RO 5.05 was current, came away with a bad impression because of a transient problem.
I'm aware that the current USB problems are actively being investigated, though only a minority of devices are affected.
Anyway, thanks for an interesting and positive article.
