So a lower power more expensive ARM board compared to AMD £99 MiniITX/CPU setup to run a less stable/more complicated version of UAE emulation on via a non existent release of AROS for playing old Amiga games via ADFs? nice 
(If it can't physically load actual Amiga floppy disks and doesn't have a Paula chip on the motherboard it isn't actually an Amiga)
Agreed, the closest we're gonna get to a new Amiga is the Natami.
As for ARM, its going places. Just look at the way people went crazy over Quake3 running on the Raspberry Pi.. it's a platform that has a bit of buzz about it, the scene needs new development and new software and x86 is already swamped with OS options. As likely as I am to be crucified and flamed for eternity for saying so its a platform change that could see the community grow, its not going to be popular with a lot of people because like you say it wouldn't be REAL Amiga but at the end of the day I'm sure people don't look at a Macbook Air in a store thinking "hmmm well it's not a REAL Mac...". It would be nice to get back the feel of "wow, look at what this thing can do!" that to me was as much part of what is Amiga as the custom chips if we can't resurrect the 68k.
(Incidentally I have no trouble whatsoever with Amiga emulation on my ARM-based OpenPandora).
