Ahh, I don't think it could have been any different. The key thing about Amiga is that it's built on custom hardware. If it stayed true to its roots than it would have died anyway sooner or later, because in the world where competitors are built on cheap generic expendable hardware, Amiga as we know it could never be a viable mainstream alternative. The only way would be an Amiga built from those same generic parts and I'm not sure I would want that.
I think custom hardware today can only work for gaming consoles and other single-purpose devices with limited lifespan.
