People will buy it because it’s the better computer system.
One has to define “better system”. In terms “business systems”, I don’t think Amiga is ready for this.
The “Business PC” (i.e.the IBM PC/AT and compatible standard) is a powerful force due to it’s relation to economics. A tool for generating income and solving business problems e.g. Lotus 123 for DOS back in mid 80s (relates to software availability issue). It’s all about economics. The available hardware and software is only a means to an end.
PS; IBM’s PC/AT standard still out guns Commodore’s Amiga sales even when the Amiga’s at its peak.
