An excellent article covering many key points; thanks for gathering your thoughts together for us, Ian.
I agree with your one negative comment, the name A9home.
Qercus, Drobe and Iyonix are good names because even an unsophisticated google search homes in on what you expect and without clutter. Yet they are not too contrived or hard to remember.
It's an extra aspect to the marketing game that those who name products have to consider these days.
It'll be interesting to see what emerges, given all of the high, and hopefully not unrealistic, hopes the A9 seems to be generating.
