Wait... I had my copy of "Existentialism for Dummies" around here somewhere.
I think it what made the Amiga an Amiga was/were the qualities and uniqueness of both it's hardware and software. No machine is perfect, but the fact that it was so awe inspiring when it first came out caused alot of us to stop and ponder and be a lot more creative than we might have been otherwise.
The new Amigas aren't "real Amigas" per se (flamebait) but a "re-telling" of the Amiga's design goals on radically different hardware and software.
My two cents...
