@EverBlue,
OK, one example scenario: A-EON buys 10,000 units of off the shelf x86 motherboards without CPU at about $1m cost, which will likely be discontinued stock in 3-6 months in the PC world.
Then Hyperion takes at least 18 months to port the OS to it.
What will happen? Will customers want an x86 board in 2 years time branded as an "Amiga" that has long since expired its shelf life in PC world terms? Or will they accept that it? Will be be able to sell 10,000 units? These are the business risks that would have to be taken.
In addition to the hardware, every third party software that has been written for PowerPC AmigaOS needs to be recompiled for the new x86 ISA under AmigaOS.
