Well for %&$#?@!%&$#?@!%&$#?@!8364;30 it doesn't hurt to try out OS4 on WinUAE to get a feel for it and see if he wants commit funds to dedicated hardware.
Makes sense. Try it on WinUAE and see if it fits to your purpose. If you still want new machine you probably know better which one you want. It worked well to Pavlor who was waiting new AmigaOne for years.
Besides, when you buy OS4 for PowerUp Amigas Hyperion get their money anyway. If you buy AmigaOne later Hyperion is getting twice as much.
