A1 is not an Amiga in my mind. I think the last Amiga computers were sold about 10 years ago.
It's not a bad idea to use the Amiga OS and name, but it's slightly confusing to ask "why don't you buy a new Amiga?"
I seem to remember on another thread, any true "new Amigas" would have to come from Gateway as they own the technology. Is that still ture?
