Call me stupid but I would rather sell one hundred X1000s at 1000EUR each than ten X1000s at 2500EUR each. Nevertheless, it would be cool if we had an expandable and powerful X2000 workstation alongside a cheaper X500 machine as we had A500 and A2000 (or even better, A1200 and A4000) two decades ago. And yes, the Sam460 should cost 300EUR with a complete system at 500EUR _including_ AmigaOS4. Oh well ....
You would have to be stupid are else extremely rich as you would be selling at a big loss. The AmigaOne X1000 and Sam are manufactured in low volumes in England and Italy, so will always be pricy compared to Dell's, Apple etc which are built by the millions in China.
