I have to leap to RComp's defence here! These are the people that have given years of free support on their products.
The new Messenger subscription scheme (that I happily signed up to in an attempt to give something back for this support) promptly delivered an upgrade; followed by a bug-fix/support build about a month later; followed by the CD that dropped through the letterbox today (don't know what's on that - haven't had time to look yet).
And I agree with SimonC about Firefox. Peter had credibility, made a promise, delivered on it and then asked for the money. He's among the good guys too.
Sadly, MicroDigital never really looked likely to do the same. It all looked too much like a reiterated RO wish-list. In fact, when I first saw the Iyonix spec, I thought the same. Only when I saw one actually working did I really believe it. Perhaps there's a lesson there after all.
