There is a precedent against Microsoft bundled software already. If you buy a system which includes bundled Windows in the price, but you do not want Windows, you are entitled to a refund for the price of the software. Why should Hyperion/Amiga Inc be treated any differently?
To my knowledge you can buy A1 without OS4. You can't buy OS4 without a licensed motherboard though. So your comparison is faulted.
