The problem with the whole situation back then is that Commodore needed a drop in replacement for the Commodre 64 for mass retail, that's what retailers wanted. Something that could hold up against PC's and Nintendo... A refresh item around 87-89. Commodore never delivered one... by then the Amiga was not marketed as a MASS item.
I don't know about that, they tried, I think it depends on what market you were in. In the UK at least the A500/A600/A1200 was sold as a mass market item (compared to other computers/consoles of its time). I was not ever really aware of anyone owning a big box amiga as they were well out my price range.
