I know what you mean. But then I see A500s as "Classic Amigas" which are a particular type of Amiga. They're a subset of "Amiga" which contains Classic Amigas and NextGen Amigas.
The thing is, if CBM has continued with the Amiga, we'd still be using hardware much like we are now. There's 0% chance they'd have continued down the custom chip route, because whereas in the mid-80s it was necessary, these days it'd be corporate suicide.
In fact, it's my opinion that if CBM had continued, they'd have done much more damage to AmigaOS and we'd be in a much worse position than we're in now.
