I will let Mac128 answer you in detail on that point, as I have expressed my full opinion on that before in other threads on this site.
But I will summarize by saying this, if we all apply your thinking and cast the 64k ROMs to the wind, there is no meaning whatsoever in buying any Mac other than a Plus. Seriously. I personally am not drawn to a machine simply because its "the first Mac." Some software is incompatible with the new ROMs.
