This is not a hybrid drive, it is two drives as evidenced by the picture of the iMac that Phil Schiller showed.
This is more akin to "tiered storage" which has existed before, just not in the consumer space which prevents more/different challenges.

Do you know how difficult it would be to set up something comparable using two drives (HDD+SSD) under, say, Ubuntu?
"Fusion Drive" provides the union of space.
They are in the same vein of "hide the slowness of rotational media" but that is a pretty huge vein.
That's just a 4% increase in space that the Fusion Drive gives you over what a cache would give you. You can call it whatever you want, but I'm going to call them similar.
