That's interesting. I guess the only real solution that Amiga Inc could see would be to put the whole $25 on the OS4 software, however overpricing the only piratable part of a "AmigaOne" system would encourage more people to download the OS illegally rather than buy it.
The problem with AInc putting $25 on the software is again the contract in '2.03(A) Royalties'.
"Standalone version. Other than for OS4.0 for which no royalties shall be due by Hyperion, Hyperion shall pay Amiga for 20 USD for each standalone version of any subsequent version of OS4 developed by Hyperion pursuant to this Agreement"
In retrospect this was a bad decision by Amiga Inc. If they had forgot about hardware licence fee and went for a software licence fee only we would probably see OS4 on these alternative hardware platforms and no law suit. On the other hand we would not have seen AmigaOnes. As Eyetech would probably not have taken on the risk if they had compete with generic solutions.
