I'll tell you what makes an Amiga in my books...
a few months ago, I was going to show Mr Beanbag to a friend's 13 year old daughter. I was clicking through windows on the workbench.
Her: what kind of computer is this?
Me: Amiga 1200
Her: What is that, how old is it?
Me: *points at (c) Commodore 1992 at top of Workbench Screen*
Her: How come it's so fast?
