I'm not considering buying one, simply because I can get way better for the spare money that I have.
I would only buy a new Amiga if it were some sort of a "revolutionary" machine. Now that word can be filled in with lots of things, but I absolutely have no special feeling with this new Amiga motherbaord.
Now if they would make a beautiful case for it, true to the Amiga heritage (did somebody say Walker?), plus some nice things like the old Amiga 1200 Magic Pack, THEN I think it really has something. But not if it's just a dull green board in a dull grey/black/blue case.
