Adam:
I'm confused about your assumption that Select for the Iyonix would be completely different from any other Select. Apart from the links to the hardware they would be identical being derived from exactly the same source. That surely is what it's all about. Whilst the interface layer will be different the user shouldn't be aware of differences - except that more software will run on the RiscPC than will run on an Iyonix or A9. And at a different speed!
