I'm now of the firm belief that MikeJ's Replay board with AROS 68k is the future of the Amiga.
Everything else is now an "also ran".
Depends on what you're looking for, I guess. As a toy or "classic replacement" it looks great. It'll be too slow for much serious use for anyone used to more modern machines though.
Natami has a better shot there, possibly, since they're more geared for performance, but that too will likely be too slow for most people.
As I've said elsewhere, I want both of them and the X1000, but I suspect main machine will remain an x86 box, though hopefully eventually running AROS most of the time.
Then again, it doesn't really matter if it works for you.
(I'm considering picking up an A1200 too, to actually have a real classic again, and get one of the new ACA accelerators for it, but I suspect sneaking the Replay and X1000 past the wife will be hard enough)
