If you want it, ask Genesi to licence it. Porting OS 4 to the Pegasos is not a matter of good or ill will. Like Kronos pointed out, Genesi doesn't care about OS 4, even if some of their customers would want it, but there is nothing that either Hyperion or AI could do about this. A public offer of free hardware on some MorphOS mailing list hardly suffices. A call or an email to those involved would have been a bit less public but a lot more genuine.
Please note that this is not only a matter of licencing - there already was a clear "no" to us long before the licencing scheme ever came up. It's also not about Donglization - a USB dongle would do the same job. It is also not about exclusivity - there is no exclusivity involved in the OS 4 licence, since Eyetech also sells the machines as Linux only.
It is true that anti-piracy methods don't do much good, but they at least prevent some of the casual copies. Put it any way, but piracy is a problem, not only on the Amiga.
All buyers of an AmigaOne will get a licence to OS 4 included. I am not ready to judge how many buyers of a 500 + dollar mobo are going to pirate their stuff - I think the amount of piracy on the Wintel market speaks for itself, they also buy 500 dollar systems and pirate; some (mind you, some) people seem to think that paying for hardware is OK because you can touch it, but paying for software is useless since it is just magnetic bits.
The comparison between Genesi (or any Amiga company) and Apple is rather far fetched - if we could divide the sales that Apple has between all of the Amiga companies in existance, we'd all be considerably better off. Apple doesn't need to care for alternative OSes besides their own.
