My first computer was an Amiga 500. IIRC a 5 Meg external hard disc was $1500. Couldn't afford that, had to live with 720K floppies. Eventually succumbed to a 286 for exactly the reason you mentioned, Amiga was a great computer with not much useful software. I was trying start a CAD rendering business. Back then the competition was from big architectural houses with $50,000 Intergraph workstations that could do distributed processing of the renderings (tortuously slow process back then) across all the PCs networked in the office. Before I gave up on the Amiga I did an animated 3D rendering of the Barcelona Pavilion, complete with midi soundtrack of Bolero. Gave up on the idea completely when I realized I needed about 6X the funding I had available to be competitive. About a year later I was restoring antique radios, starting VALVE magazine and thinking about our first kit.
The new Amiga will need to be as unique as the old one, with some outstanding feature the competition doesn't have. Back then it was the relatively inexpensive very high quality (for the time) graphics.
