It would have a custom GPU that will remain conspiciously better than anything available for less than $1000 for three years. You could imagine an in-house "NVidia game console" that does this, perhaps? But surely a terrible business plan for whatever it has in its technology pipeline.
It would have to be extremely better too, or people wouldn't notice the difference. Socially computing has changed so much, with mobile and everything, so it's hard to imagine what a spiritual successor to an Amiga would be today.
It was also very simple to understand and well documented, and small and responsive. I think if a computer was made today where everything was treated with the utmost care for latency, that could make a difference.
Imagine a user interface which had effectively zero latency, and no loading times at all.
You see these things happening today with things like the Apple VR headset and its custom real-time compute co-processor. VR requires a kind of low-latency operation that was par for the course w/ home computers, including the Amiga itself (partly because analog CRT displays were themselves very low latency compared to current garden-variety LCD's) but is seen as very high-end today.
