the hardcore Amiga community will decide what is and is not "Amiga". Just because Amiga Inc. hold the legal trademarks, it does not mean they define "what Amiga is". As far as i'm concerned, Amiga today is: MorphOS, AOS4 and AROS (and WinUAE setups on x86).
The acid-test for any modern Amiga platform will always come from old Amiga coders, not average "users" who might be fooled , for example, by a Linux setup with some AmigaOS 5 wallpaper slapped on. If the Libraries/APIs are "Amiga" - IT IS AMIGA as far as I'm concerned...does not matter who made the hardware. MorphOS is as close to REAL Amiga as you could possibly get and also adds some nice/modern enhancements.
Pls, don't let Amiga Inc. trick you into beleiving they are Amiga just because they had the financial muscle to buy the trademarks. Although I haven't used it yet, AOS4 fortunately looks to be maintaining the real Amiga essence. They will have to prove themselves again with AOS5 before I adopt THAT as Amiga.
