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.
